16
Q

includes distinct groups of neurons that coordinate eye movements like blinking and focusing, and trigger reflexes to sounds.

A

midbrain

17
Q

inhibit unwanted
body movements and help coordinate
sensory input and motor output to
manage the fine motor control that
enables you to write with a pen or play
a musical instrument

A

midbrain

18
Q

helps regulate complex
body movements.

A

basal ganglia

19
Q

plays roles in glucose regulation and sleep and includes several regions that help control movement.

A

hindbrain

20
Q

tucked underneath the occipital lobe at the very back of the brain, is the second-largest
part of the brain in volume, containing over half the brain’s neurons.

A

cerebellum

21
Q

influences breathing and posture.

A

pons

22
Q

carries nerve pathways connecting the brain to the spinal cord
and contains neural networks that help control basic functions like swallowing, heart rate, and breathing.

A

medulla

23
Q

The earliest vertebrates probably had brains much
like the one in the modern lancelet
Amphioxus

A

.

24
Q

Information moves from one region of your brain to
another via chains of ____ that can transmit signals over long dis-
tances.

A

neurons

25
Q

electroencephalograph (EEG).

A

measures electrical patterns in the brain

26
Q

originate mainly in the parietal
and occipital lobes when your brain
is relaxed and eyes are closed, and are
characterized by frequencies between 8 and 13 Hz

A

Alpha waves

27
Q

are somewhat faster than alpha waves, with frequencies ranging from
14 to 30 Hz. Beta waves are typically produced by the frontal and parietal
regions of your brain when it processes sensory input or concentrates on a
task.

A

Beta Waves

28
Q

Are slower
than alpha waves, ranging from 4 to
7 Hz,

A

Theta Waves

29
Q

which occur
during deep sleep, are very slow, with
frequencies less than 3.5 Hz.

A

delta waves

30
Q

_____waves are typically of higher
amplitude (stronger) than _____ waves

A

Alpha and delta / beta or theta

31
Q

part of a feedback loop that takes
information from cortical areas that
elicit movement and produces signals
that feed back to the cortex to excite
or inhibit specific movements.

A

Basal ganglia
