Studies suggest that biased memory processing is in the fusiform gyrus and the prefrontal cortex often contribute to depression (Gerrits, 2019). The fact that the current primary case, PL518, had selective damage to the left fusiform gyrus is also more in alignment with other research indicating that left hemisphere regions are more consistently implicated in generating mental imagery than corresponding right hemisphere regions [4,7,22,24,61,62,63,64,65,66,67,68]. Fusiform Gyrus The fusiform gyrus (FG) is thought to underlie our ability to process faces and is therefore crucial for interacting appropriately in social situations. The fact that the FG and pSTS are frequently co-activated suggests that they may interact synergistically in a distributed face processing network. Would you like to know how to translate fusiform gyrus to other languages? In the human brain, the mid-fusiform sulcus (MFS; sulcus sagittalis gyri fusiformis) divides the fusiform gyrus (FG) into lateral and medial partitions.Recent studies show that the MFS is identifiable in every hemisphere and is a landmark that identifies (a) cytoarchitectonic transitions among four areas of the FG, (b) functional transitions in many large-scale maps, and (c) the location of . The results suggest tuning of this cortical area to letter probabilities as a result of perceptual experience and provide a possible neural correlate . Before Gintaras Didziapetris became an object of archaeology of the future, he took photos of a city on the other side of . The idea of a face that exceeds its portrait and disappears into its moving parts is key.
In other words, the right fusiform gyrus is involved in the holistic processing of faces, while the left fusiform gyrus tends to process a feature-based representa-tion of the face. One surprise was that some parts of the fusiform gyrus connect to a part of the brain called the cerebellar cortex, which is not thought to be part of the traditional vision-processing pathway. Fusiform Gyrus. Search all projects Search my projects. fusiform gyrus. Files. Recent reports of a high response to bodies in the fusiform face area (FFA) challenge the idea that the FFA is exclusively selective for face stimuli. [3] [4] fusiform gyrus Norwegian.
