Tactile Localization and Sensory Adaptation

Tactile Localization

• Requires two markers: one for the subject and one for the experimenter.
• The experimenter stimulates a particular body area with the marker.
• The subject needs to recognize the stimuli and locate its origin.

Adaptation to Sensory Receptors

• All receptors adapt to repeated exposure:
  • Basilaria core muscles:
  • Meissner's core muscles
  • Root core muscles
• Adaptation involves a decrease in response to a constant stimulus over time.

Ice Bath Experiment

• A volunteer places their elbow in an ice bath for 30 seconds.

Experimental Procedure Discussion

• Subjects are divided into groups.
• Experimenters will do different tests(2 and 3) based on what the instructor tells them to do.

Tactile Experiment Details

• Experiment involves touching the subject's skin, possibly on the back of the hand or face, and asking about their sensations.
• The subject usually closes their eyes during the experiment.

Numerical Data Collection

• The experiment involves measuring distances/locations where the touch is felt.
• Values such as 1.4, 1.5, 2, 4, and 5 are recorded.
• Scale referenced: 5, 10, 15, 20, 25
