when we see double because our immune system attacks glia cells ==> less transmission

17
Q

action potential

A

temporary shift from - to positive in neuron membrane (NA in and K out)

18
Q

depolarization

A

opening of sodium channels

19
Q

repolarization

A

negative internal space becomes negative again

20
Q

hyperpolarization

A

the cells are more negative than resting potention ==> fixed by ion channels and the sodium potassium pump

21
Q

synapses

A

site of transmission and connection between neurons

22
Q

neurotransmitters

A

chemical transmissions that carry information from pre-synaptic sending neurons to the post synaptic recieving cell

23
Q

what do drugs alter?

A

the synapses in our brains by reducing connections

24
Q

Characteristics of neurons

A

fast response, transportation of cargo over long distances, high energy demand, terminally differentiated

25
sciatic nerve
longest nerve in the body from spinal cord base to our big toes
26
cerebral cortex
the grey matter on the brain and outer 6 layers of nerve cells
27
white matter
innery layer of the cerebrum due to myelin
28
frontal lobe
responsible for cognitive/ perosnality changes and higher functioning as well as voluntary movements
29
temporal lobe
responsible for memories and processing sensations related to memories
30
parietal lobe
processes information from our senses
31
occipital lobe
primarily vision
32
insula
connects our body signals to our outside world
33
visual agnosia
inability to recognize visually presented objects as whole
34
hemispatial neglect
only perceiving information from half of the brain or one hemisphere
35
somatoparaphrenia
delusion where one denies ownership of a limb
36
corpus callosum
white matter fibers connecting the left and right brain hemispheres
37
split brain
severing of the corpus callosum so hemispheres work independently
38
left hemisphere
dominant for language and speech ==> comes from right side pictures
39
right hemisphere
movement and drawing ==> comes from left visual field
40
hydranencephaly
condition where the portions of the brains cerebral hemispheres are absent and filled with cranial fluid instead
41
rasmussen syndrome
disruption of signaling from the right side of the brian
