Q

What is grey matter?

A

Grey matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.

Q

What does grey matter do?

A

The Grey Matter serves to process information in the brain. Structures within the grey matter process signals generated in the sensory organs or other areas of the grey matter. This tissue directs sensory (motor) stimuli to nerve cells in the central nervous system where synapses induce a response to the stimuli.

Q

What are some important functions of the brain stem?

A

The brainstem is responsible for relaying motor and sensory information to and from different regions of the brain. It regulates:

  • breathing
  • cardiac function
  • sleep and eating
  • consciousness
  • temperature
  • the central nervous system
17
Q

What is a gyrus?

A

The grooves and ridges on the outside of the cerebrum.

18
Q

What is a sulcus?

A

Small grooves on either side of the Gyrus.

19
Q

What are fissures?

A

Large grooves on either side of the Gyrus.

20
Q

What is the function of the prefrontal cortex?

A

The prefrontal cortex is responsible for executive control of behaviour, planning and working memory.

21
Q

What is the function of the premotor and motor cortex?

A

The premotor cortex and motor cortex are responsible for movement.

22
Q

What is the function of the Broca’s area?

A

Broca’s area is involved in the production of speech, the process by which thought is translated into speech sounds.

23
Q

What is the function of the auditory cortex?

A

The auditory cortex is involved in the processing of sound

24
Q

What is the function of the visual cortex?

A

The visual cortex receives, integrates and processes visual information relayed from the retinas.

25
Q

Where is our emotional response to music processed?

A

The limbic system.

26
Q

What is the function of the limbic system?

A

The limbic system is responsible for processing emotion, behaviour, and long-term memory.

27
Q

What parts of the brain make up the limbic system?

A
  • thalamus
  • hypothalamus
  • hippocampus
  • amygdala
  • basal ganglia
28
Q

What is the function of the thalamus?

A

The thalamus relays sensory information to and from different regions of the brain.

29
Q

What is the function of the cingulate gyrus?

A

The cingulate gyrus is also involved in emotion processing, as well as regulation of the autonomic nervous system, which controls blood pressure, heart rate, etc.

30
Q

What is the function of the hypothalamus?

A

The hypothalamus regulates the body’s hormones and body clock.

31
Q

What is the function of the amygdala?

A

The amygdala is involved in learning, memory, and most importantly, fear responses and the regulation of emotion.

32
Q

What is the function of the basal ganglia?

A

The basal ganglia is a group of neurons involved in coordinating movement, located on either side of the thalamus.

33
Q

Where is the cingulate gyrus located?

A

The cingulate gyrus is located above the corpus callosum.

34
Q

When we feel a physical response to hearing or making music (such as increased heart rate), what part of the brain has come into play?

A

The cingulate gyrus.

35
Q

When listening to music, what does the cerebellum do?

A

When listening to music, the cerebellum coordinates foot tapping in time to the music and is involved in some emotional responses to music.
