Answer:
The correct answer is ''controlled individual muscle movements; store a repertoire of movement categories stored a repertoire of movement categories.''
Early research on the motor cortex suggested that it controlled individual muscle movements; however, more recent work suggests that the motor cortex may actually store a repertoire of movement categories.
Explanation:
Voluntary movements are consciously initiated in the motor cortex and association cortex, commanding the appropriate groups of motor neurons in the spinal cord to perform the desired activity. The motor cortex is divided into six layers separated by neurons, each fulfilling different functions. Also, it is subdivided into three areas (the primary motor cortex, the premotor cortex and the supplementary motor area) which have specific functions for performing motor activities. Electrophysiological recordings have shown that the movements of individual muscles are correlated with the activity of broad regions of the primary motor cortex. Similarly, stimulation of narrow regions of the primary motor cortex produces movements that require the activity of numerous muscles. The premotor cortex, located in front of the motor cortex, produces coordinated movements that comprise sequences of movements of an individual muscle or combined movements of a number of different muscles at the same time. It is in this area where a large part of the knowledge is stored to control learned skillful movements, that is, according to previous experiences, it is in charge of storing movements to end up organizing the final activity of the primary motor zone, automating and harmonizing voluntary movements .
Answer: A) bottom-up processing
Explanation: Bottom-up processing simply refers to the processing of sensory data or information as it's being received be the sensory organs.
For instance, when an image is being show to an individual, the eyes sees it and the brain picks up the signals to bring together all the pieces of information. Information like; it has stripes, has four legs, has a tail, has a face, has long canine teeth and then the image is recognised that
Oh it's a Tiger.
Berdine developed cataract in both eyes preventing her to even see the face of her mother in the first place before the brain could bring together the different imagery information and recognise her mother's face, so Berdine is clearly deficient in bottom-up processing of sensory information.
