Touch

Front 1

Haptic perception

Back 1

activeexploration of the environment by touching and grasping objects with our hands

Front 2

Hapticreceptors

Back 2

detectpressure, temperature and vibrations

Front 3

Touch receptors

Back 3

espondto stimulation within their receptive fields and long axons enter the brain viathe spinal cord, have receptive fields with central excitatory zones surroundedby donut shaped inhibitory zones

Front 4

Pain receptors

Back 4

populate body tissues that feel pain

Front 5

thermoreceptors

Back 5

sense temperature

Front 6

Contralateral Organization

Back 6

lefthalf of body is represented by right and vice versa

Front 7

What and Where pathways of touch

Back 7

upper and lower parietal lobes

Front 8

Pain

Back 8

withdrawalreflex is coordinated by the spinal cord

Front 9

Pain pathways

Back 9

sendssignals to the somatosensory cortex identifying where the pain is occurring andwhat sort of pain it is. The second pain pathway sends signals to themotivational and emotional centers of the brain such as the hypothalamus andamygdala and the frontal lobe

Front 10

Referred pain

Back 10

occurswhen sensory information from internal and external areas converges on the samenerve cells in the spinal cord (heart attack feeling pain in left arm ratherthan heart)

Front 11

Gate Control Theory

Back 11

a theory of pain perception based on the ideathat signals arriving from pain receptors in the body can be stopped or gatedby interneurons in the spinal cord via feedback from two directions

Front 12

Periaqueductal gray (PAG)

Back 12

whereneural feedback comes from in midbrain. Under extreme conditions, naturallyoccurring endorphins activate the PAG to send inhibitory signals to the neuronsin the spinal cord that then suppress pain signals to brain (non-natural isopiate)

Front 13

Vestibular system:

Back 13

three fluid-filledsemicircular canals and adjacent organs located next to the cochlea in theinner ear -canals are arrangedin three perpendicular orientations and studded with hair cells that detectmovement of the fluid when the head moves or accelerates -detected motionenables us to maintain our balance -vision also helpsus keep our balance

Front 14

Cortical Processing of Motion

Back 14

Activation of areaV5/MT (occipital cortex) (helps see things in a smooth and continous way)

Front 15

Akinetopsia

Back 15

Damage to V5/MT(very uncommon) (see a moment in snapshots)

Front 16

Motion sickness

Back 16

body thinks and eyesthink in respect to movement) Tricks to reduce theeffects
