4 skin senses (touch) | pressure/ warmth/ cold/ pain |
Pain | nociceptors—sensory receptors in skin, muscles, and organs--detect hurtful temperatures, pressure, or chemicals. |
Path of pain | Nocioceptors→spinal cord→ brain→ “OUCH!” |
Phantom Limb Pain | Brain creates painful sensations after an amputation |
Phantom Limb Pain cortex | misinterpretation of spontaneous neural activity in the sensory cortex |
Empathy | We perceive more pain when others experience more pain |
Expectation | We get cues from our culture on how to respond to pain |
Pain is impacted | by how much attention we give to it |
Taste is also called | gustation |
Supertasters | Contain more pores |
Sweet | energy source |
Salty | sodium source |
Sour | Potentially toxic acid |
Bitter | potential poison |
Umami | protein |
5 tastes | Sweet/ salty/ sour/ bitter/ umami |
Process of tasting | Food chemicals → Transduction inside taste bud pore → thalamus → sensory cortex |
Smell is also called | olfaction |
olfactory receptors in olfactory bulb | transmit a message to the rest of the brain |
How does smell reach our brain? | Air/ Olfactory Receptor/ Brain’s olfactory bulb/ Temporal lobe (primary smell cortex)/ Limbic system (memories) |
Kinesthetic sense | Position of body in space (Cerebellum) |
Vestibular sense | Balance (Semicircular canals in ears (crystals cause vertigo) |
synesthesia | the brain circuits for two or more senses become joined/ Stimulation of one sense triggers an experience of another |
