Recent studies have used fMRI to explore specific brain networks, such as the salience network and default mode network, to understand their roles in schizophrenia-related symptoms. Alterations in these networks may affect self-referential thoughts and responses to external stimuli, potentially contributing to symptoms like hallucinations and ...
Visual processing abnormalities in schizophrenia are commonly found, and contribute to poor social function. [ 1 ] There is evidence that schizophrenia affects perception of contrast and motion , control of eye movements , detection of visual contours, and recognition of faces or facial expressions .
The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. [1] The DLPFC is not an anatomical structure, but rather a functional one.
Several models have been put forward to explain the link between altered brain function and schizophrenia. [27] The prevailing model of schizophrenia is that of a neurodevelopmental disorder, and the underlying changes that occur before symptoms become evident are seen as arising from the interaction between genes and the environment. [126]
Schizophrenia is a mental disorder that most commonly affects social and emotional functioning. Besides emotional and psychological influences, it is believed that genetics and early development play a role in the onset of schizophrenia. [8] The physical aspects of the disease are actual differences in the brain of the affected.
MRI studies have found a smaller brain volume and larger ventricles in people with schizophrenia – however researchers do not know if the shrinkage is from the schizophrenia or from the medication. [157] [158] The hippocampus and thalamus have been shown to be reduced in volume; and the volume of the globus pallidus is increased. Cortical ...
Hyperphantasia is the condition of having extremely vivid mental imagery. [1] It is the opposite condition to aphantasia, where mental visual imagery is not present. [2] [3] The experience of hyperphantasia is more common than aphantasia [4] [5] and has been described as being "as vivid as real seeing". [4]
BrainMaps – National Institute of Health (NIH) database including 60 terabytes of image scans of primate and non-primates, integrated with information covering structure and function. NeuroNames – Defines the brain in terms of about 550 primary structures (about 850 unique structures) to which all other structures, names, and synonyms are ...
