Reaction Time Lab Review

Station 1: Dominant Side

Nondominant side Dominant side

Station 2: Feeling objects

Station 2: Feeling objects Smaller, densely packed neurons Larger, less densely packed neurons *Cannot determine: *specific objects *exact placement of objects

Densely Packed Neurons

Station 3: Temperature

Station 3: Temperature

Station 4: Blind Spot

Station 4: Blind Spot

Summaries Station 1: Dominant side Your dominant side muscles are bigger because they are constantly used daily for everyday tasks. Because of this they are able to use are memory of how to do tasks and therefore complete tasks faster. When you use both sides of your body, the nerve path is longer so it takes the signal longer to get to and from the brain

Summaries Station 2: Feeling Objects We were able to feel both toothpicks closer together on our fingers because there are more neurons in that area and they are smaller.

Summaries Station 3: Temperature It was harder to pick up the pennies after putting our hand in the ice water because our blood supply was decreased and therefore our neurons were unable to transmit a signal. Also the chemicals that are sent to each neuron are moving slowly so the signals get sent slowly.

Summaries Station 4: Blind Spot The spot where the optic nerve enters the eye prevents there from being any rods or cones in that area. So in some parts of our visual field we are unable to see objects because the rods and cones are missing, which enable us to see objects and colors.
