processing units of the nervous system. The human brain contains about 10 billion neurons that are organized into complex networks. This complexity results from the fact that each neuron can be directly linked with up to ten
thousand other neurons. However, the brain is also composed of structures that seem to play specific roles in the integrated functioning of the brain. (Grady, Dobrovolsky, and Aronoff, 1997, p. 416). Let's see them! ]]> 2020-06-01 04:34:35 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604046111 benitezsilvana08 https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604055769 In humans, the cortex is a grey wrinkled mass that sits like a cap over the rest of the brain. The wrinkled appearance results from the cortex being folded in upon itself. This folding allows a great amount of cortical matter to be compressed into the limited space provided by the human skull.
The cortex is what makes us different from other animals and is where the secrets of language representation and processing are to be found. ]]> 2020-06-01 04:45:54 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604055769 benitezsilvana08 https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604071718 The folds of the cortex have two parts: sulcus, which are areas where the cortex is folded in, and gyrus, which are areas where the cortex is folded out toward the surface.
A very prominent feature is the the longitudinal fissure. It separates the left and right  cerebral hemispheres.  The corpus callosum, which is a bundle of nerve fibres ,allows the two hemispheres to communicate with one another.]]> 2020-06-01 05:07:05 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604071718 benitezsilvana08 https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604085100 In general, the left hemisphere seems to excel in analytic tasks such as arithmetic, whereas the right hemisphere excels in tasks that require an overall appreciation of complex patterns such as the recognition of familiar faces and melodies. ]]> 2020-06-01 05:22:20 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604085100 benitezsilvana08 https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604095863  While the left hemisphere controls the right side of the body, the right hemisphere controls the left side.]]> 2020-06-01 05:34:42 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604095863 benitezsilvana08 https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604097160 2020-06-01 05:36:02 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604097160 benitezsilvana08 https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604100092  Although the left and right hemispheres have different abilities and
different responsibilities, complex skills such as language do not always fall neatly into one hemisphere or the other, because language involves the coordinated functioning of both hemispheres. ]]> 2020-06-01 05:39:26 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604100092 benitezsilvana08 https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604113440 Each hemisphere contains substructures that appear to have distinct responsibilities. The substructures of the cortex in each hemisphere are called lobes. In this image, we can identify those areas of the cortex that have a particular role to play in language processing. ]]> 2020-06-01 05:53:16 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604113440 benitezsilvana08 https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/604127398

This signal is then transferred via the arcuate fasciculus to Broca’s area where preparations are made to generate a spoken version of the word. A signal is then sent to the part of the motor cortex to physically articulate the word. ]]> 2020-06-02 19:34:18 UTC https://padlet.com/benitezsilvana08/xedkrp4sfpwu3cj5/wish/607579931
