Motor information- away from the brain and to the body
New cards
2
Parietal
info perceived through the skin, which then goes to the somatosensory cortex in the parietal lobe
New cards
3
Neural networks
Networks of nerve cells that integrate sensory input and motor output
New cards
4
CNS
Spinal cord- 99% of nerve cells located here Brain
New cards
5
Somatic
sensory nerves, convey info to the brain, and orders motor nerves
New cards
6
Gamma-Aminobutyric Acid (GABA)
Stops many neurons from firing to increase motor control Inhibitory Ex: valium and anti-anxiety drugs
New cards
7
dendrite
a short extension of a nerve cell where impulses are received from synapses
New cards
8
Occipital lobe
info is perceived through the eyes, which them goes to the visual cortex
New cards
9
cell body
contains the nucleus, needed for growth, keeps cell body alive
New cards
10
Frontal
connects to nervous system (spinal cord) which is how we make movements
New cards
11
neurogenisis
process by which new neurons are generated but only happens in the hippocampus or olfactory bulb
New cards
12
CEO of the brain
frontal cortex
New cards
13
Endorphins
Natural opiates- depress nervous system activity and eliminate pain Elevates feeling of pleasure Runners high
New cards
14
Afferent nerves
Sensory information- to the brain
New cards
15
Oxytocin
Associated with social bonding Love and social bonding hormone Released during orgasm Released in new mothers after birth Associated with positive moods, affectionate touch, and preoccupation with one relationship
New cards
16
Automatic
info from the body's internal organs and monitoring automatic process
New cards
17
PNS
Connects the CNS to other parts of the body. Executes the the commands of the CNS.
New cards
18
axon
carries info away from cell and towards other neurons
New cards
19
Norepinephrine
Stops the firing of neurons in the CNS, but excites the heart muscles, intestine, and urogenital tract (PNS) Inhibitory and excitatory Monitors alertness
New cards
20
destroyed neurons
cannot be restored
New cards
21
Acetylcholine (ACh)
Stimulates the action of muscles, learning, and memories Excitatory Ex: black widow or botox
New cards
22
damaged neurons
can be restored over time
New cards
23
Collateral sprouting
the growth of intact neurons in neighboring damaged neuron areas
New cards
24
substitution of function
damaged brain region is taken over by another region of the brain
New cards
25
Glutamate
Stimulating neurons to help learning and memory Excitatory Most prevalent neurotransmitter- therefore often target for psych disorders
New cards
26
Temporal
info is perceived through ears, which goes to the auditory cortex
New cards
27
thalamus
located at the top of the brain, switch board, processes all senses except smell
New cards
28
Dopamine
Helps with movement, memory, and pleasurable reward and motivation Excitatory Related to extraversion
New cards
29
Seratonin
Regulates sleep, mood, attention, and learning Key to maintaining the brain's neuroplasticity Excitatory Teams with acetylcholine and norepinephrine to regulate sleep and wakefulness
