case Loc of
LateralVentricle: begin
writeln('This cavernous space is filled with cerebrospinal fluid, flowing medially');
writeln('toward a small opening. As you are carried by this flow, you notice a dorsal');
writeln('passage that looks promising.');
end;
ThirdVentricle: begin
writeln('In this narrow fluid-filled chamber you are being carried rapidly in a');
writeln('caudal direction. The thalamus looms large on either side of you, while');
writeln('ventrally you can make out nuclei of the hypothalamus.');
end;
CerebralAqueduct: begin
writeln('This is a narrow passageway connecting the third and fourth ventricles.');
writeln('The flow of cerebrospinal fluid is carrying you caudally quite rapidly!');

FourthVentricle: begin
if PillWorking = 0 then begin
writeln('WARNING! WARNING! You are in the fourth ventricle! Do not proceed caudally');
writeln('without your anti-immune system pill. Without it, you will be devoured by');
writeln('the phagocytes and white blood cells of the immune system!');
end;
writeln('This is a large space filled with cerebrospinal fluid. The cerebellum towers');
writeln('above you, and several structures are apparent ventrally.');

CaudateHead: begin
writeln('This large forebrain structure is a major component of the extrapyramidal');
writeln('motor system and, with the putamen, makes up the corpus striatum. You were');
writeln('able to enter the caudate by way of the nigrostriatal bundle because you were');
writeln('carrying dopamine. The structure narrows considerably in the caudal');
writeln('direction, but there appears to be an opening there.');
end;
CaudateTail: begin
writeln('This narrow tail of the caudate is quite slippery, and the footing is very');
writeln('treacherous. The tail curves laterally and ventrally out of view in a caudal');
writeln('direction.');
end;
Amygdala: begin
writeln('This structure is often grouped with both the basal ganglia and the limbic');
writeln('system. It probably subserves aggression or rage. Passages lead caudally');
writeln('and medially.');

Putamen: begin
writeln('The putamen is a component of the corpus striatum and the lentiform nucleus.');

writeln('room from the medial direction.');
end;
Pallidum: begin
writeln('This extrapyramidal structure, together with the more lateral putamen, makes');
writeln('up the lentiform nucleus. The lentiform nucleus and corpus striatum together');

writeln('almost invisible passage leads in a medial direction.');
end;
Nigra: begin
writeln('This darkly pigmented area produces much of the dopamine found in the brain.');

CerebralPeduncle: begin
writeln('The heavily myelinated highway that you find yourself on extends both');

writeln('Passages extend away from you in all directions except dorsally and rostrally.');
end;
Pons: begin
writeln('This mesencephalic landmark contains many groups of cell bodies, as well as');
writeln('fibers that extend to the cerebellum. The corticospinal fibers that make up');

writeln('group of cells in the medial direction.');
end;
Medulla: begin
writeln('This primitive part of the brain, in the myelencephalon, controls vegetative');
writeln('processes essential to life. The sound of running water is quite strong');
writeln('dorsally, This region nears the end of a long rostral-caudal highway, and you');
writeln('can see some fibers decussating caudally. A passage leads medially.');
end;
Raphe: begin
writeln('This midline group of cell bodies forms the core of both the pons and the');
writeln('medulla. For some reason, you feel quite drowsy.');
end;
LateralLemniscus: begin
writeln('These myelinated fibers form part of the auditory pathway. You hear sounds');
writeln('that seem to originate in a medial direction. A small hill rises on the');
writeln('rostral horizon. A narrow pathway leads caudally.');
end;
VentralNoradBundle: begin
writeln('This caudal-rostral pathway consists of noradrenergic fibers that lead from');
writeln('the locus coeruleus in the pons to the forebrain.');
end;
InferiorColliculus: begin
writeln('You are on a small hill in the auditory system. This structure forms part');

writeln('This brainstem nucleus is the most peripheral part of the auditory system');
writeln('that you can enter. There is no obvious exit.');
end;
PeriAqueductalGray: begin
writeln('This region surrounding the cerebral aqueduct plays a role in the modulation');
writeln('of pain. Electrical stimulation of this area produces profound analgesia.');

writeln('in the medial direction.');
end;
AuditoryCx: begin
writeln('Whirr - TICKTOCK - Meeoowwww - TraLaLaLa - CRASH - "Fourscore and seven years"');
writeln('Voices, music, and every imaginable sound envelope you. Words seem quite');
writeln('loud in both the dorsal and caudal direction, and a bundle of fibers');
writeln('extends medially. The landscape is hazy in the rostral direction.');
end;
SuprachiasmNuc: begin
writeln('This small structure is thought to be involved in the regulation of circadian');
writeln('rhythms. You can see the optic chiasm ventrally.');
end;
Pituitary: begin
writeln('Also known as the hypophysis, this endocrine organ is often called the');
writeln('"master gland" of the body. Under the control of the hypothalamus, it ');
writeln('secretes a variety of hormones. There is no obvious way out.');
end;
Pyramids: begin
writeln('Here fibers of the corticospinal tract cross to opposite sides of the');
writeln('brainstem before descending to terminate in the spinal cord. There is no');
writeln('obvious way out.');
end;
CingulateGyrus: begin
writeln('This band of limbic cortex allows passage in all directions except medially');
writeln('and caudally.');
end;
OpticTract: begin
writeln('This bundle of fibers carries visual infomation caudally to the lateral');
writeln('geniculate nucleus in the thalamus. The fibers appear to decussate somewhat');
writeln('rostrally to here. A large hill is barely visible in the ventral distance.');
end;
OpticChiasm: begin
writeln('Optic nerve fibers from the nasal half of each retina cross here on their way');

end;
LateralGeniculate: begin
writeln('Visual information is relayed caudally from this point to the occipital lobe');
writeln('of the cortex. The optic tract enters from a rostral direction, and the rest');
writeln('of the thalamus lies medial to your current position. A large hill is just');
writeln('apparent in a ventral direction.');
end;
SuperiorColliculus: begin
writeln('This large hill, together with the inferior colliculus, forms the tectum, the');
writeln('roof of the mesencephalon. The superior colliculus is involved in visual');
writeln('tracking and reflexive eye movements. A steep path descends ventrally into');
writeln('a nondescript, gray region. Other passages lead both dorsally and rostrally.');
end;
OpticRadiation: begin
writeln('This pathway conveys visual information from the lateral geniculate nucleus');
writeln('to the visual cortex in the occipital lobe.');
end;
VisualCx: begin
writeln('Lights, colors, forms, shapes and patterns of every conceivable shade, hue');
writeln('and brightness dance around you. This is the cortical area concerned with');
writeln('visual information processing. There is no obvious way out.');
end;
Septum: begin
writeln('This limbic system structure seems to inhibit rage or emotionality, for');

writeln('A tunnel leads laterally, and other paths lead dorsally and caudally.');
end;
MammillaryBody: begin
writeln('This hypothalamic region is implicated in both emotionality and sexual');
writeln('behavior. An intriguing road lies dorsally, and a narrow path rostrally.');
writeln('Moving medially causes intense hunger pangs.');
end;
Hippocampus: begin
writeln('Memories well up within you in this structure that is thought to play a role');
writeln('in memory consolidation. A myelinated pathway leads medially, and a small');
writeln('passageway leaves in a rostral direction.');

writeln('mammillary bodies of the hypothalamus. The fibers extend ventrally,');
writeln('rostrally, and laterally.');
end;
VMN: begin
writeln('You feel quite satiated within this hypothalamic nucleus, felt to play a role');
writeln('in the inhibition of food intake. Moving laterally gives rise to feelings of');
writeln('hunger, while ventral movement gets your hormones flowing.');
end;
LHA: begin
writeln('Severe hunger grips you here, but it seems to subside as you approach a');
writeln('medial passage. A large structure looms above you, and a passageway leads');
writeln('caudally.');
end;
SensoryStrip: begin
writeln('Shocks race through you, fingers caress you, pins prick at you, and feathers');
writeln('brush your skin here in the cortical area that mediates somatosensation.');

writeln('Voluntary motor control resides here, exerting its influence via the bundle');
writeln('of fibers descending ventrally below you. You can move in all directions');
writeln('except dorsally.');
end;
FrontalLobe: begin
writeln('This region of the cortex is concerned primarily with motor control and');
writeln('planning, but is also implicated in various aspects of that nebulous feature');
writeln('of us all, our personality. You can move both caudally and medially.');
end;
Brocas: begin
writeln('This area of the frontal lobe plays an important role in speech production.');
writeln('Faint sounds originate ventrally, and you sense movement medially. An');
writeln('important area seems to lie caudal to this, but its name escapes you.');
end;
Wernickes: begin
writeln('You know what this place is, but you cannot find the words to name it. It');
writeln('is involved in speech, you think. Several passageways lead out of this area,');
writeln('but you cannot think of the names of the directions in which they lead.');
end;
AssocCx: begin
writeln('Recollections dance around you here. You hear music that reminds you of a');
writeln('place that you once visited. You met someone there, and can see her face.');
writeln('The way out is none too clear, and your memories haunt you.');
end;
Accumbens: begin
writeln('This region, poised between the limbic system and the basal ganglia, is');
writeln('thought to allow emotions to gain access to the motor system. The only way');
writeln('out is laterally, the way you came in.');
end;
Cerebellum: begin
writeln('This delicately structured "small brain" sits atop your brainstem, and');
writeln('controls coordinated movements. It may also play a role in learning. The');

Assoc1: begin
writeln;
writeln('This is a different region of the association cortex.');
end;
Assoc2: begin
writeln;
writeln('This part of the association cortex is different from the one you just left.');
