Nervous system pt 1

To use light to control neurons in living tissue

To record electrical activity from muscles

To measure blood flow in the brain

To stimulate muscle contraction with electricity

They change the shape of neurons

They glow when a specific frequency of light shines on them

They block neural signals

They destroy neurons

Channelrhodopsin (ChR2)

Halorhodopsin (Halo)

Fluorescent protein

Voltage-gated sodium channel

It coordinates actions and senses by sending electrical signals throughout the body.

It only controls voluntary muscle movements.

It is responsible for producing hormones.

It stores fat and energy for the body.
