Alison sees Lara and cannot fully understand what she was saying because of the competing noise. Alison uses the same visual pathway that Lara did that was previously explained. However, the primary visual cortex is not the only part of the brain that processes what Alison is seeing. There are surrounding areas that also process visual information once it reaches the primary visual cortex. Areas 1&2 process orientation, spatial frequency and color. Area three integrates information that you are receiving. Area four is vital for object recognition and color perception. Area five is important for motion …show more content…
The direct motor pathway is also referred to as the pyramidal system. The pyramidal tracts controls voluntary gross motor movement. The pyramidal tract is made up of two tracts, the corticospinal tract and the corticonuclear tract (Rouse, 2015). The tracts are significant for motor movements, as well as, motor movements required for speech. The corticospinal tract originates in the cortex and travels past the pyramids located in the medulla to innervate spinal nerves through the spinal cord. The cotricospinal tract controls movement of the limbs (Rouse, 2015).The corticonuclear tract also originated in the cortex and travels past the pyramids located in the medulla to innervate the cranial nerves. The corticonuclear tract controls fine motor movements and controls the movement of the speech mechanisms. The corticonuclear tract is the most important tract for speech and swallowing (Rouse,
