Adrenaline

fight or flight

Noradrenaline

concentration

Dopamine

pleasure

Serotonin

mood

Acetylcholine

learning

Endorphins

pain killer

Epithalamus consists of

pineal gland and habenular nuclei

Function of Epithalamus

secretion of melatonin by pineal gland

regulation of motor pathways and emotions

Function of Hypothalamus

thermostat, vital functions:

linking NS to endocrine system via pituitary gland

controls body temp, hunger, thirst, fatigue, sleep

Limbic system function

emotion, behavior, memory, aiding in response to stress and pleasure

Amygdala function

process fear anger and pleasure

hippocampus function

formation of new memories, short to long term

hypothalamus function

regulation of hunger, thirst, temp and circadian rhythm

thalamus function

signals in & out of the cortex

cingulate gyrus function

emotion forming, processing, learning & memory, relating to social environment

septal nuclei function

involved in rewards and reinforcement in learning & pleasure seeking behavior

mamilllary bodies function

memory and recall pathways between Hippocampus and entorhinal cortex

fornix function

highway between hippocampus and other parts of limbic system, pull memory from hippocampus

parahippocampal gyrus function

encoding & retrieval of memory

entorhinal cortex function

portion of temporal lobe involved in memory pathways as well as navigations and time perception

3 components of brain stem

midbrain (mesencephalon)

pons (metencephalon)

Medulla oblongata (myencephalon)

What cranial nerves are stem from the midbrain?

III & IV

What cranial nerves stem from the pons?

V VI VII VIII

What cranial nerves stem from the telencephalon?

I

bypass thalamus

What cranial nerves stem from the Diencephalon

II

What cranial nerves stem from the Medulla Oblongata?

IX X XI XII

Function of Cerebellum

balance and posture

coordination of voluntary motor movements

motor learning/procedural memory

3 Lobes or Cerebellum

Anterior, posterior, Flocculonodular

Cerebellum blood supply from

vetebrobasilar

3 layers of cerebral cortex

1. molecular

2. purkinje cell layer

3. granule cell layer

ataxia

errors or rates, range, force & direction of movement

Dysdiadochokinesia

inability to perform rapid alternating movements

nystagmus

Involuntary rapid eye movements

association fibers

connect b/w two portions of same hemisphere

commissural fibers

link two matching locations of the two hemispheres

Projection fibers

leave the cerebrum

parkinsons

OH

overactivation, hypokinesisa

huntingtons

UH

underactivation, hyperkenesia

Anterior pituitary is

glandular

posterior is neural tissue

GABA

inhibitory

glutamate

excitatory

Parasympathetic CN
