Sensory receptors -what do they do -where are they located and why
-convert energy of stimulus into action potential -located in sensory organs because they help increase the energy of stimulus to reach the threshold
sensation -when does it occur -2 examples of evidence -what is it called when receptors adapt to continuous stimulation and filters out some info
-when the nerve impulse reaches the cerebral cortex of the brain but not the receptor itself -block transmitter chemical and brain mapping -sensory adaptation
-what can the brain do to process information quickly -what is the downside
-it can split sensory ifnormation to different parts of the brain -sometimes it isnt inegreated propwrly and what we sense isnt what we interpret
