16
Q

how is the primary visual cortex organized

A
  • retinotopically,
    • how you actually see the thing is mirrored by the brain activity seen!!
17
Q

Subcortical Areas of the Forebrain

A

thalamus
hypothalamus
limbic system
- hippocampus
- amygdala

18
Q

thalamus

A
  • sensory relay for the brain
    • All of our senses, with the exception of smell, are routed through the thalamus before being directed to other areas of the brain for processing.
19
Q

The limbic system

A
  • involved in processing both emotion and memory.
    • smell projects directly to the limbic system

limbic system contains hippocampus and amygdala

20
Q

hippocampus

A
  • emotions, learning and memory
    • recipe card for the memory
21
Q

amygdala

A
  • experience of emotion and in tying emotional meaning to our memories.
  • emotion regulation
    • especially sensitive to fear and anger
  • involved in learning (emotion)
22
Q

hypothalamus

A
  • regulates a number of homeostatic processes
  • interface between the nervous system and the endocrine system
  • regulation of sexual motivation and behavior.
23
Q

endocrine system

A

creates the hormones

24
Q

midbrain

A

neurotransmitters are made in hindbrain!!!!
- substantia nigra
- ventral tegmental area (VTA)
- Raphe Nuclei
- locus coeruleus

25
Q

ventral tegmental area (VTA) and substantia nigra

A
  • contain cell bodies that produce the neurotransmitter dopamine
  • both are critical for movement.
  • Degeneration is involved in Parkinson’s disease.
  • structures are involved in mood, reward, and addiction
26
Q

Raphe Nuclei

A

creates serotonin

27
Q

locus coeruleus:

A

creates norepinephrine

28
Q

HINDBRAIN

A

unconscious and reflexes!
- reticular formation
- medulla
- pons
-cerebellum

29
Q

reticular formation

A
  • projects from the hindbrain through the midbrain up into the forebrain
  • regulating the sleep/wake cycle, arousal, alertness, and motor activity.
30
Q

medulla

A

heart beating, blood circulation, breathing

31
Q

pons

A

relays information from cerebellum to the rest of the brain

32
Q

cerebellum

A

receives messages from muscles, tendons, joints, and structures in our ear to control balance, coordination, movement, and motor skills; fine motor skills

- movement begins in motor cortex, but when the signal is refined, this goes to the cerebellum
- also thought to be an important area for processing some types of memories.
    - procedural memory, or memory involved in learning and remembering how to perform tasks
