namely simple visual stimuli, are present in the visual field; however, when complicated objects are put in place, this initiates a response in the single-cell neurons of the IT cortex. This provides evidence that not only are the single-cell neurons of the IT cortex related in having a unique specific response to visual stimuli but rather that each individual single-cell neuron has a specific response to a specific stimuli. The same study also reveals how the magnitude of the response of these single-cell neurons of the IT cortex do not change due to color and size but are only influenced by the shape. This led to even more interesting observations where specific IT neurons have been linked to the recognition of faces and hands. This is very interesting as to the possibility of relating to neurological disorders of prosopagnosia and explaining the complexity and interest in the human hand. Additional research from this study goes into more depth on the role of "face neurons" and "hand neurons" involved in the IT cortex.

to highlight the parts of the brain that are important in achromatopsia in monkeys, however, it obviously sheds light on the areas of the brain related to achromatopsia in humans. In the study, one group of monkeys (group AT) received lesions in the temporal lobe anterior to V4 and the other group (group MOT) received lesions to the occipito-temporal area that corresponds in cranial location to the lesion that produces cerebral achromatopsia in humans. The study concluded that group MOT had no impairment of their color vision while the subjects in group AT all had severe impairments to their color vision, consistent with humans diagnosed with cerebral achromatopsia. This study shows that temporal lobe areas anterior to V4, which includes the inferior temporal gyrus, play a large role in patients with Cerebral Achromatopsia.
552:, are characterized by a patient's inability to integrate semantic memories, which results in patients being unable to form new memories, lacking awareness of time period, as well as lacking other important cognitive processes. Chan et al 2001 conducted a study that used volumetric magnetic resonance imaging to quantify the global and temporal lobe atrophy in semantic dementia and Alzheimer's disease. The subjects were selected and confirmed to be in the middle of the spectrum of their respective disorders clinically, and then further confirmation came from a series of neuropsychological tests given to the subjects. The study treated the inferior temporal cortex and the middle temporal cortex as one and the same, because of the, "often indistinct," border between the gyri. 519:, also called face blindness, is a disorder that results in the inability to recognize or discriminate between faces. It can often be associated with other forms of recognition impairment, such as place, car, or emotional recognition. A study conducted by Gross et al. in 1969 found that certain cells were selective for the shape of a monkey hand, and they observed that as the stimulus they provided began to further resemble a monkey hand, those cells became more active. A few years later, in 1972, Gross et al. discovered that certain IT cells were selective for faces. Although it is not conclusive, 628: 688: 676: 532:
discriminate between faces, or even recognize faces that were familiar to him before the accident. L.H. and other patients with prosopagnosia are often able to live relatively normal and productive lives despite their deficit. L.H. was still able to recognize common objects, subtle differences in shapes, and even age, sex, and "likeability" of faces. However, they use non-facial cues, such as height, hair color, and voice to differentiate between people. Non-invasive brain imaging revealed that L.H.'s prosopagnosia was a result of damage to the
385:, among others. These cellular connections have recently been found to explain unique elements of memory, suggesting that unique single-cells can be linked to specific unique types and even specific memories. Research into the single-cell understanding of the IT cortex reveals many compelling characteristics of these cells: single-cells with similar selectivity of memory are clustered together across the cortical layers of the IT cortex; the temporal lobe neurons have recently been shown to display learning behaviors and possibly relate to 616: 652: 29: 474: 499:, in order to create an array of understanding of the physical world. The hippocampus is key for storing the memory of what an object is/what it looks like for future use so that it can be compared and contrasted with other objects. Correctly being able to recognize an object is highly dependent on this organized network of brain areas that process, share, and store information. In a study by Denys et al., functional magnetic resonance imaging ( 640: 352: 457: 664: 503:) was used to compare the processing of visual shape between humans and macaques. They found, amongst other things, that there was a degree of overlap between shape and motion sensitive regions of the cortex, but that the overlap was more distinct in humans. This would suggest that the human brain is better evolved for a high level of functioning in a distinct, three-dimensional, visual world. 604: 577: 242: 221:. This region processes the color and form of the object in the visual field and is responsible for producing the "what" from this visual stimuli, or in other words identifying the object based on the color and form of the object and comparing that processed information to stored memories of objects to identify that object. 286:
