Flashcards in Sub-cortical Structures Deck (15):
1

Structures in the hindbrain?

Medulla oblangata

Pons

reticular formation

Cerebellum

2

Medulla oblongata

Location: extension of spine

Controls:
Cardiovascular - breathing and heart rate
Reflexes - vomit, cough, sneeze
Sensory and motor pathway - muscles (face, mouth, neck and shoulders)

3

Pons

Location: on top of medulla

Controls: information to face, eyes, ears and brain

Neurones pass from one side of brain to other side of brain

Regulation of sleep - REM and immobilisation

4

Reticular formation

Location: deep in medulla and pons

Controls: regulate attention and sleep

Damage = coma or death

Sends info from lower section of nervous system (body) to higher cortical regions for processing

5

Cerebellum aka little brain

Controls: motor, balance, gait and posture

6

Cerebellum hypoplasia

Underdeveloped cerebellum = uncoordinated movements

7

Midbrain

Superior colliculus

Interior colliculus

Tectum

Tegmentum

Substantia nigra

8

Forebrain

Thalamus

Hypothalamus

Basal ganglia

Hippocampus

Amygdala

9

Thalamus

Location: centre of brain

Controls: sends sensory information Touch, taste, vision, hearing to primary vortices for further processing

I.e

Touch, pain, pressure sent from sensory neutrons —> thalamus —-> primary somatosensory cortex

10

Hypothalamus

Location: below thalamus

Controls: 4 F’s - avoidance and motivational Behaviours

Fighting, fleeing, feeding, mating

11

Basal ganglia

Location:

Controls: movement, emotional regulation and cognition

Help learn coordinated movement

12

What does damage to basal
Ganglia result in?

Parkinson’s disease

13

Hippocampus

Location: one in each hemisphere to the side of thalamus and basal ganglia

Controls: consolidating short term memory into long term memory so you can rely on it later

14

Damage to hippocampus can cause?

Anterograde amnesia - unable to form new memories

15

Amygdala

Location: 2 near end of hippocampus

Controls: fear and aggression

Constantly scanning for information which may or May not be relevant to you
