Limbic System
What is the function of the amygdala?
It acts as the emotion center for the brain
What is the role of the auditory cortex?
Receives and processes sounds
Which hemisphere typically contains Broca and Wernicke's area?
Left hemisphere
What are the major two divisions of our overall nervous systems?
The central nervous system and the perhipheral nervous system
What is the period/age range where our brain is making millions of connections with no pruning?
From birth to age 2-3, "critical period"
What is the function of the thalamus?
It acts as the sensory information relay in the brain
What is the role of the thalamus in the hearing process?
Sensory relay station that sends sound/electrical signals to the auditory cortex
Where is the auditory cortex located?
The temporal lobe
What is the difference between the sympathetic and parasympathetic nervous system?
Sympathetic: mobilizes, engages fight or flight response
Parasympathetic: demobilizes, engages in relaxed states
What neuroimaging technique measure almost immediate changes in oxygen and blood flow in the brain?
What is the function of the hippocampus?
Encodes short term memory to long term memory
What role does the auditory nerve (cranial nerve VIII) serve?
Transmits electrical signals to the brain
Which hemisphere is typically dominant for music?
Right hemisphere
What is the role/functions of the autonomic nervous system?
Controls the automatic functions of your body, e.g. digestion, sleep, heart rate, involuntary movement
What are the three types/mechanisms of neuroplasticity?
Synaptic plasticity, neural network plasticity, and cortical remapping
What is the function of the hypothalamus?
Supporting homeostasis and the autonomic nervous system
What role does the cerebellum play in the hearing process?
Transmitting the signal to the brainstem
Which hemisphere is typically dominant for the auditory cortex?
Right hemisphere
What makes up the central nervous system and the peripheral nervous system?
CNS: brain and spinal cord
PNS: nerves that connect peripheral structures to brain and spinal cord
An EEG measures how many different electrical activity waves?
Five (delta, theta, alpha, beta, gamma)
What is the function of the pituitary gland?
Hormone production and regulation
What is the role of the brainstem in hearing?
Assesses sound for fight, flight, freeze response, and send 70% of the sound to the contralateral hemisphere
What are the locations of the sensory strip (cortex) and motor cortex?
Motor cortex is in the frontal lobe, sensory strip is the parietal lobe
What is the role/functions of the somatic nervous system?
Bonus points: is it part of the CNS or PNS?
Responds to: touch, pressure, movement, temperature, pain, and muscle movement
Bonus points: peripheral nervous system
Name 5 components of the hearing process in order
Can include: cochlea - auditory nerve - cerebellum - brainstem - thalamus - auditory cortex
