|
||||
| show | Dorsal Stream ("Where" or "How" Pathway)spatial awareness, motion, and action guidance, Ventral Stream ("What" Pathway)object recognition, color, and fine details
🗑
|
||||
| What visual disorders would result if you damaged the following areas: V1, V5, V8, temporal lobe, parietal lobe, bilateral damage to lateral regions of occipital lobe. | show 🗑
|
||||
| show | visual disorder in which an individual is unable to perceive colors (world appears in grayscale)
causes: acquired damage to V8, can be congenital mutation
🗑
|
||||
| associative object agnosia | show 🗑

🗑
|
||||
| show | inability to perceive motion
🗑
|
||||
| What is neurogenesis? | show 🗑
|
||||

|
||||
| show | Thalamus ,Somatosensory cortex- feeling

| What factors affect sensitivity? | show 🗑
|
||||
| Why can’t we tickle ourselves? | show 🗑
|
||||
| show | is the process by which the nervous system detects and processes painful stimuli. It is a crucial mechanism for protecting the body from harm by signaling potential or actual tissue damage.
🗑
|
||||
| show | GCT revolutionized pain research by showing that pain is not just a direct response to injury but is actively modulated by the nervous system
🗑
|
||||
| What are endorphins? | show 🗑
|
||||
| What is the function of periaqueductal gray matter? | show 🗑
|
||||
| What is congenital analgesia? | show 🗑
|
||||
| Episodic analgesia? | show 🗑
|
||||
| show | referred pain is the pain felt on surface of the body that is actually due to pain in of the internal organs with neurons carrying nociception from the organs not having a unique brain pathway,
🗑
|
||||
| show | fibromyalgia is a syndrome: a person experiences long term with bodywide pain and tenderness in joints, muscles, tendons, and other soft tissues; Reason unknown, may be due to brain areas involved in pain responding differently in those with fibromyalgia,
🗑
|
||||
| Phantom limb pain? | show 🗑
|

|
||||
| show | Lack of muscle coordination during voluntary movements
🗑
|
||||
| show | Coordinates and learns skilled movements and balance, has a role in the timing of movement, and maintains movement accuracy
🗑
|
||||
| show | vestibular system plays a critical role in maintaining balance, spatial orientation, and coordinating movement. It helps you stay upright, steady, and oriented in space, particularly when you're moving.
🗑
|
||||
| show | Basal ganglia is a set of nuclei that coordinates voluntary movements of the limbs and body, generating the force required for movement and/or initiates movement at appropriate time and place.
🗑
|
||||
| Describe the role of the basal ganglia in Huntington’s chorea and Parkinson’s disease. | show 🗑
|
||||
| show | Hyperkinetic symptoms are excessive involuntary movements while hypokinetic symptoms is the paucity of movements
🗑
|
||||
| show | Huntington’s chorea is a hereditary, chorea (ceaseless involuntary, jerky movements) and progressive dementia ending in death due to the degeneration of neurons in frontal cortex and basal ganglia,
