Question

Quizplus · Accepted Answer

Sensation refers to the process by which sensory receptors detect and respond to external stimuli. This is the initial activation of receptors by external stimuli, which is a crucial first step in the overall process of perception. Activation of receptors leads to transduction, which is the conversion of physical energy into neural signals that can be processed by the brain to create perception. Adaptation and habituation both refer to changes in sensory processing over time, rather than the initial activation of receptors.
