Study Notes

Brain Activation and Music

The primary somatosensory cortex showed activation when musicians' fingers were touched.
The duration of playing an instrument is positively correlated with the strength of activation.

Visual Cortex and Blindfolded Period

During the blindfolded period, the visual cortex activation decreased.
The study suggests that there is a connection between the visual cortex and the processing of tactile information.

Cochlear Implants

The purpose of a cochlear implant is to bypass damaged or non-functioning parts of the ear and directly stimulate the auditory nerve.
Currently, cochlear implants can replicate up to 22 different frequencies.
The cochlea is primarily responsible for frequency coding in the brain.

Prosthetic Limbs

The purpose of a prosthetic limb is to replace or support a damaged or missing limb.
Prosthetic limbs can be used to enhance the quality of life for individuals with amputations.

Synesthesia

The area of the eye that allows us to see colors well is the fovea.
One possible cause of synesthesia is cross-talk between brain regions.
The term used to describe the temporary loss or gain of synesthesia is "switching".
One example of synesthesia in everyone is the association of red with the concept of "stop" and green with the concept of "go".
The term used to describe the phenomenon where colors are associated with different letters or numbers is "grapheme-color synesthesia".
One possible cause of acquired synesthesia that is NOT mentioned is a head injury.
One possible effect of synesthesia when a number is moved towards the periphery of vision is that it may appear larger or more vivid.
One possible explanation for why some individuals may repress their synesthesia is that they may feel it is abnormal or stigmatized.
The term used to describe the phenomenon where motion is perceived as sound is "auditory-tactile synesthesia".
One possible difference in brain connectivity observed in synesthetes compared to control individuals is increased connectivity between sensory regions.
