These are the sites where NEUROTRANSMITTERS are SYNTHESIZED, STORED and RELEASED.

Synaptic Vesicles

*Fig 4.7 p. 86*

1

Ca++ causes vesicles to fuse with ____________.

Plasma membrane

2

These BRAIN WAVES have a frequency of 1/2-4 cps and are a characteristic of DEEP SLEEP. (SLOW WAVE SLEEP)

Delta Waves

*Fig 5.9 p.107*

3

These BRAIN WAVES had a frequency of 4-7cps and they are found in TWILIGHT sleep, experienced upon waking or drift.

Theta Waves

*Fig 5.9 p.107*

4

These BRAIN WAVES have a frequency of 8-12 cps and are involved in RELAXED WAKEFULNESS.

Alpha waves

*Fig 5.9 p.107*

5

These BRAIN WAVES have a frequency of 13-30 cps and are involved with an ALERT WAKEFUL state found in REM sleep

Beta Waves

*Fig 5.9 p.107*

5

These BRAIN WAVES have a frequency of 40+ cps and are associated with the highest state of focus.

Gamma Waves

*Fig 5.9 p.107*

6

This method of EEG RECORDING requires one electrode placed over the BRAIN AREA and one placed on the EARLOBE.

Monopolar Recording

7

This method of EEG RECORDING requires one electrode placed over one brain area and one electrode place over ANOTHER BRAIN AREA.

Bipolar Recording

8

During SYNAPTIC TRANSMISSION, synapses impose a DELAY of ___ msec.

5

9

What are the FOUR (4) steps of SYNAPTIC TRANSMISSION?

1.) DEPOLARIZATION of the membrane allows Ca++ to enter.

2.) Ca++ causes VESICLES to FUSE w/ MEMBRANE

3.) NEUROTRANSMITTERS RELEASED

4.)NEUROTRANSMITTERS BIND to RECEPTORS/ Na+ gates OPEN

10

Synaptic/ Postsynaptic Potentials require a __________ neurotransmitter.

Excitant

11

This is a GRADED POTENTIAL that can BUILD UP W/ EXCITATION, arriving SIMULTANEOUSLY from DIFFERENT DIRECTIONS. It is the COMBINED INFLUENCE of many neurotransmitters releasing at different locations on a postsynaptic membrane at a PARTICULAR TIME.

Spatial Summation

*Fig 4.3 p. 80 and Fig 4.4 p.81*

12

This occurs with REPEATED EXCITATION and is the COMBINED EFFECTS of neurotransmitter release OVER TIME.

Temporal Summation

*Fig 4.3 p. 80 and Fig 4.4 p. 81*

13

This is when the neurotransmitter makes the dendrites and cell body of a postsynaptic cell MORE PERMEABLE to POSITIVELY CHARGED sodium ions.

EXCITATORY Postsynaptic Potential m

*Fig 4.2 p. 80*

14

EXCITATORY POSTSYNAPTIC POTENTIAL results in ___________ or __________.

Partial Depolarization or Graded Potential

*Fig 4.2 p. 80*

15

True or False: it is easier to stimulate a postsynaptic cell with INHIBITORY POSTSYNAPTIC POTENTIAL.

FALSE, it is more DIFFICULT to stimulate a post synaptic cell wit INHIBITORY postsynaptic potential

*Fig 4.2 p. 80*

16

During INHIBITORY POSTSYNAPTIC POTENTIAL the neurotransmitter _____________ the dendrites and cell body of the postsynaptic cell.

Hyperpolarize

*Fig 4.2 p.80*

17

What is the FATE of a NEUROTRANSMITTER? (3)

1.) STIMULATE or INHIBIT dendrite or cell body of another neuron

2.) Be taken back into neuron from which it came

3.) Be INACTIVATED in reaction catalyzed BY an ENZYME.

18

1/2 to 4

19

THETA waves have a frequency of ___ to ___ cps.

4-7

20

ALPHA waves have a frequency of ___ to ___ cps.

8-12

21

BETA waves have a frequency of ___ to ___ cps.

13-30

22

GAMMA waves have a frequency of ___ cps.

40+
