Q

Mirror neuron

A

watching someone else is like doing an activity yourself (getting tense/charged about football).

When you make a face/see a face, your brain functions the same

most basic social brain system, not necessary if you dont want to relate to others

20
Q

Brodmann’s area

A

Identified parts of the brain as to what emotion it evokes. Some people believe it, many dont

21
Q

Sulcus/Gyros

A

Sulcas: grove (sulk, down)
Gyros: lumps

22
Q

Prefrontal cortex

A

problem solving, emotion, complex thought

23
Q

Motor association cortex

A

coordination of complex movement

24
Q

Cortical Homunculus

A

Pictoral representation of the anatomical divisions of the primary motor cortex and the primary somatosensory cortex

25
Q

Primary motor cortex

A

initiation of voluntary movement (frontal lobe)

Frontal sulcas between this and primary somatosensory cortex

26
Q

Primary somatosensory cortex

A

receives tactile information from the body (parietal lobe)

largest portion of sensory: hands

Frontal sulcas between this and primary motor cortex

27
Q

Sensory association area

A

Processing of multisensory information

28
Q

Visual association area

A

complex processing of visual information

29
Q

Visual cortex

A

detection of simple visual stimuli

30
Q

Wernicke’s area

A

language comprehension, understanding

31
Q

Broca’s area

A

language production and articulation

32
Q

Auditory association area

A

complex processing of auditory information

33
Q

auditory cortex

A

detection of sound quality (loudness, tone)

34
Q

Left/Right body brain connection

A

left side damage = right side impairment

35
Q

Aphasia

A

disorder caused by damage to the parts of the brain that control language. Making it hard to read, write, and say what you intend.

36
Q

Wernicke’s aphasia

A

loss of the ability to understand language, person can speak clearly, but the words put together make no sense
“word salad”

37
Q

Broca’s aphasia

A

Prevents a person from producing speech, person can understand language, words are not properly formed, speech is slow and slurred
(typically from stroke)

38
Q

Lateralization

A

Right hemisphere believed to be better at non verbal tasks and interpretation of emotional expression, visuo-spatial functions and non verbal memory, creative, music (for non musicians)

Left hemisphere: logical, linear, sequential, music (for musicians)

39
Q

Draw and label a neuron!

A

Draw and label a neuron!

40
Q

Synapse

A

structure that permits a neuron to pass an electrical or chemical signal to another cell (neural or otherwise)

41
Q

Neurotransmitter

A

chemicals which allow the transmission of signals from one neuron to the next across synapses

42
Q

Soma

A

The soma is the cell body of a neuron

43
Q

White matter

A

contains nerve fibers. Many of these nerve fibers (axons) are surrounded by a type of fat called myelin.

44
Q

Grey matter

A

Grey matter contains neural cell bodies, in contrast to white matter, which does not and mostly contains myelinated axon tracts. (cerebral cortex)

45
Q

Limbic system

A

brain structures that lies on both sides of the thalamus.
Includes the hippocampus and amygdala.
It supports a variety of functions, including emotion, behavior, motivation, long-term memory. Primarily responsible for our emotional life, and has a great deal to do with the formation of memories.

46
Q

Neuroplasticity

A

The brain’s ability to reorganize itself by forming new neural connections throughout life.

47
Q

Cerebral cortex

A

layer of the brain often referred to as gray matter. It is the outer portion of the cerebrum.

48
Q

Hemispheres

A

Two hemispheres seperated by the corpus callosum
