The phrase "abnormal brain function" is correct and usable in written English.
It can be used in contexts related to medical, psychological, or neurological discussions to describe atypical functioning of the brain.
Example: "The study aimed to investigate the effects of stress on abnormal brain function in patients with anxiety disorders."
Alternatives: "irregular brain activity" or "atypical brain function".
Migraine is one of the common primary headaches [4], the underlying mechanisms of which are poorly understood but are believed to involve abnormal brain function [5] including functional cortical hyperexcitability arising from among other things, reduced inhibition from the cortex [6].
Organic psychoses are characterized by abnormal brain function that is caused by a known physical abnormality, which in most cases is some organic disease of the brain.
Neurological disease often appears clinically as encephalopathy (abnormal brain function and structure).
The presence of AChEis causes the neurotransmitter to hang around and fire excessively, and therefore can cause abnormal brain function and uncontrolled muscle action.
While neurodevelopmental delay and abnormal brain function occur in the absence of overt brain lesions, these conditions have been recently associated with changes in microstructural brain development.
Fundamental to the concept of idiopathic or primary headache, including migraine, tension-type headache and cluster headache, is the currently accepted view that these conditions are due to abnormal brain function with completely normal brain structure [45].
The olfactory system offers scientists a unique window on both normal and abnormal brain functioning, in part because it is so clearly laid out, with sensory impulses traveling from receptors in the nose to the olfactory bulbs, where they are decoded, and then to olfactory centers in higher brain regions.
As schizophrenia has been related to abnormal functioning in core conflict adaptation areas such as anterior cingulate and dorsolateral prefrontal cortex, further research is required to better understand the precise impact of such abnormal brain functioning at the behavioral level.
Progress in headache research suggests that migraine pathophysiology involves inherited abnormal brain functions and that the initiation of headache depends on flow of nociceptive signals that originate in pain-sensitive intra- and extra-cranial organs conveyed through peripheral nociceptors to central trigeminovascular neurons.
Therefore, chromosomal mosaicism confined to the fetal brain can be considered a possible cause of alterations in prenatal brain development, leading to fetal loss or abnormal brain functioning after birth.
We will emphasize the newly appreciated importance of neurotransmitter signalling in WM, particularly glutamate and ATP signalling, to understanding both normal and abnormal brain functions.
