Answer 1

Front brain, telencephalon (front brain) and diencephalon (thal and hyp. thal)

Question 2

Mesencephalon, dev. in mammals and humans

Answer 2

Mid brain, tectum, tegmentum and cerebral aqueduct

Question 3

Rhomboscephalon

Answer 3

Myenscephalon (spinal brain - medulla and 4th vent), metenscephalon (across brain - cerebellum, pons, 4th vent, ect.)

Question 4

translate the cephalons into english

Answer 4

Rhom. = hind
-myen = spinal
-meten = across
mesen = mid
pro = fore
-telen = end
-dien = mid

Question 5

Function of the Ret. Form

Answer 5

each nuclei has special functions (like waking from sleep)

Question 6

Function of the Pons

Answer 6

bridges cerebellum to the forebrain

Question 7

Function of the Medulla

Answer 7

Vital functions, breathing and Cardiovasc. system

Question 8

Function of the Tectum, and substructures distinction

Answer 8

Visual and sensory mapping, superior (vis) and inferior (aud) colliculi - also tactile map

Question 9

Function of the tegmentun and substructures

Answer 9

Largely movement related.
-Red nucleus - limb motion
-Substantia nigra - motion initiation
Periaqueductal grey - species-typical behaviours

Question 10

Lateral Geniculate Nucleus - location and function

Answer 10

Right tip of the thalamus

- receives info from the optic tract and sends it to the occipital lobe

Question 11

Dorsomedial thalamic nucleus function

Answer 11

Receives and transmits olfactory signals

Question 12

Smooth and gyrated brain terminology

Answer 12

Lissencephalic and gyrencephalic

Question 13

To what does the dentate gyrus belong

Answer 13

The hippocampus

Question 14

Where is the cingulate cortex located and what is its function

Answer 14

above the corp. cal. next to the midline

-involved in emotion formation and linking motivational states to behaviour, plus aspects of learning and memory

Question 15

Function of the Pyriform Cortex

To what does it transmit information?

Answer 15

Receives info from the olf. bulb, sends to the amygdala and dorsomedial thalamus

Question 16

Function of the Vomeronasal organ

Answer 16

detects pheromones - highly linked in SEX

-connects to the accesory olf. bulb then sends the info to the amygdala and then hyp. thal.

Question 17

What are cytoarchitectonic maps

Answer 17

The mapping of cell characteristics in the brain

Question 18

What are the 3 basal ganglionic structures and what is their function
with what do they coordinate?

Answer 18

1. Globus Pallidus
2. Putenam
3. Caudate nucleus
   They coordinate with the thalamus, subthalamic nucleus and substantia nigra to control voluntary movements

Question 19

Draw, labelling the directions, the tegmentum structures

or list in order from ant to post

Answer 19

Ant - post, in order

1. Sub. Nigra
2. Red Nuclei
3. Reticular formation
4. PGM / cerebral aquaduct

Answer 20

Organizing and evaluating behaviours, planning

Question 21

What are the issues associated with temporal lobe damage

Answer 21

Problems with sound recognition and complex visual info like faces

Question 22

What are the issues associated with Parietal lobe damage

Answer 22

Identifying/locating skin stimulation, problems with pointing and limb placement in space

Question 23

What are the issues associated with Occipital lobe damage

Answer 23

Problems identifying shapes and colours

inability to register/ perceive sounds
