Sensation refers to the process of detecting and receiving information from the environment through our sensory organs.


1. Sensory Receptors:

Sensory receptors are specialized cells or groups of cells that convert various forms of environmental stimuli into neural signals that can be processed by the brain.

2. Stimulation:

Stimulation is the activation of sensory receptors by environmental stimuli such as light, sound, taste, smell, or touch.

3. Transduction:

Transduction refers to the conversion of physical energy from stimuli into electrical impulses that can be interpreted by the nervous system.

4. Sensory Thresholds:

Sensory thresholds are the minimum levels of stimulation required to elicit a sensory response. These thresholds vary for different sensory modalities and individuals.

5. Sensory Adaptation:

Sensory adaptation is the gradual decrease in sensitivity to prolonged or constant stimulation. It allows us to focus on new or changing stimuli more effectively.

6. Sensory Coding:

Sensory coding refers to the translation of physical attributes of stimuli into patterns of neural activity. This coding allows the brain to interpret and differentiate between various sensory inputs.

7. Sensory Perception:

Sensory perception is the process of recognizing, organizing, and interpreting sensory information to give it meaning and make it relevant to our experiences and behavior.
