Primary somatosensory cortex corresponds to these Brodmann's areas: | 1,2 &3 |
The ________ show that sensations from the entire body surface are represented in an orderly array of cortical patches posterior to the central sulcus: | Homonculus |
The first synapse of the spinothalamic tract is found in the following location: | Posterior horn of the spinal column. |
With respect to plasticity, the human brain: | is plastic through-out life. |
Primary somatosensory cortex is characterized by somatotopic organization. IN which of the following somatosensory areas has topographic organization been demonstrated? | Dorsal posterior insula |
Which pathway is related to the sense of gravitational orientation? | Vestibular pathway |
a) the cerebellum is NOT part of the vestibular system. c)All afferents to cerebellum synapse onto neurons in the cortex. | Are false about the cerebellum. |
These "pain transducers" are found in the skin and tissues but are not found in the brain: | Nociceptors |
Specific nociceptors in the skin respond to the following: | Intense pressure Temperature Chemical stimuli |
The "mirror" pain system is comprised of: | bilateral anterior insula, left anterior cingulate, left inferior parietal lobe. |
When your heart is broken, it might be more accurate to say someone broke your: | insula |
Which of the following is/are TRUE concerning cerebellar f(x) in the motor system? | It participates in adaptive control It participates in the evaluation of differences between intention and action. (e.g. sensory input anticipated to accompany movement vs. the actual sensory input received during movement. Motor learning. |
Which is TRUE about cerebellar contribution to movement planning? | Neurons in the dentate nucleus may fire ~100ms before the movement. Lateral cerebellar lesions affect sequential movements Lateral cerebellar cortex receives input from premotor cortex & projects -> dentate nucleus and thalamus back to premotor cortex |
These account for disorders in the cerebellum: | hypotonia ataxia intentional tremor (failure of adaptive control at the end of movements) face/mouth problems (speech) if the vermis is affected. |
The cerebellar zone that is larger in humans than other primates is the: | Lateral zone |
This zone of the cerebellum contributes to conscious planning of movement: | Lateral zone. |
