INDERA STIMULUS RESEPTOR LOKASI RESEPTOR PROSES
Mata Light wave Photoreceptors

Retina Optic nerve ada transduksi (Nerve impulse, ke blindspot, thalamus)

Primary visual cortex

Visual association areas

Telinga Sound wave Hair cells Cochlea (middle ear) Auditory canal, Tympanic membrane, middle ear

Getar, transduksi jadi impulse

Primary auditory cortex (brain areas: meaningless bits of sound)

Auditory association areas (meaningful sound)

Lidah Chemical senses (various chemicals) Taste buds Papillae Molekul bercampur dengan saliva di receptor

Transduksi jadi Impuls saraf

Lobus Parietal
