Q

o Agreed with Plato and Socrates about how individuals are
born with knowledge, the mind and body are separate, and
how the mind continues after death
o Dissected animals and concluded that the cerebrospinal fluid
in the brain’s cavities contained animal spirits.
 These spirits flowed from the brain through nerves
(which he thought were hollow) to the muscles,
provoking movement.
 Memories formed as experiences opened pores in the
brain into which the animal spirits flowed as well.
 Descartes was right that nerve paths are important and
that they enable reflexes

Q

o Joined the Cornell University faculty and introduced
structuralism.
o As physicists and chemists discerned the structure of matter,
so … aimed to discover the structural elements of
mind
 … method was to engage people in self-
reflective introspection (looking inward) training them
to report elements of their experience as they look at a
rose, listened to a metronome, smelled a scent, or tasted
a substance.

instead a degree from Radcliff college, its undergraduate
sister school for women, … resisted the unequal
treatment and refused the degree.
o She was posthumously awarded the Ph.D. she earned more
than a century later.

A

Ribosomes

27
Q

A network of thin tubes that transport newly synthesized

Endoplasmic Reticulum

28
Q

Has its soma in the spinal cord. It receives excitation from other neurons through its dendrites and conducts impulses along its axon to a muscle.

Q

Is specialized at one end to be highly sensitive to a particular type of stimulation.

A

Sensory Neuron

30
Q

Dendrites

31
Q

The short growths that increase the surface
area available for synapses.

A

Dendritic Spines

Sodium-potassium Pump

46
Q

The level of stimulation required to required to
trigger a neural impulse.

A

Threshold

47
Q

A period of inactivity after a neuron has fired or a period during with it resists the production of
further action potentials.

A

Refractory Period

48
Q

A neuron’s reaction
of either firing (with a full-strength response) or not firing. The amplitude and velocity of an action potential are independent of the intensity of the stimulus that inhibited it

Synapse

Q

At a synapse, one neuron releases chemicals that affect a second neuron. Those chemicals are known as.

A

Neurotransmitters
