Q

Hindbrain – Myelencephalon: Pons

A

obtains information from body movements and the visual system to control eye movements.

17
Q

Midbrain – Mesencephalon

A

Tectum
Tegmentum

18
Q

Midbrain – Mesencephalon: Tectum

A

Contains:
two pairs of bumps called colliculi (little hills)
superior colliculi (visual function)
inferior colliculi (auditory function)

19
Q

Midbrain – Mesencephalon: Tegmentum

A

Periaqueductal grey – pain and defensive behaviour
Red nulceas & substantia nigra – motor function

20
Q

Forebrain - Diencephalon

A

Thalamus
Hypothalamus
Pituitary Gland
Limbic system
Basal Ganglia
Cerabral Cortex

21
Q

Forebrain - Diencephalon: Thalamus

A

Receives sensory information and sends it to the relevant parts of the brain

22
Q

Forebrain - Diencephalon: Hypothalamus

A

Heavily involved in emotion and motivation (feeding, drinking, and temperature)

23
Q

Forebrain - Diencephalon: Limbic system

A

Regulates motivated behaviours

24
Q

Forebrain - Diencephalon: Basal Ganglia

A

Striatum (caudate and putamen)
Globus Pallidus (motor and cognitive functions, learning and memory)

25
Q

Forebrain - Diencephalon: Cerabral Cortex

A

Involved in higher cognitive processes (language, attention, perception)
2 hemispheres, 4 lobes
The two hemispheres are joined by the corpus callosum
