New neurostimulation technology works safely and non-invasively to modify brain activity. The findings may provide some foundational knowledge for the development of future technologies that could expedite cognitive processes.
The strength of a person's mental imagery is associated with excitability in the prefrontal cortex and visual cortex. Highly excitable neurons in the visual cortex may reduce a person's ability to imagine mental images. The findings shed light on how aphantasia, a condition where a person can not imaging mental images, may occur.
Transcranial focused ultrasound (tFUS) can help elevate mood and decrease activity in brain networks associated with psychiatric disorders when directed at the ventrolateral prefrontal cortex.
Transcranial magnetic stimulation (TMS) shows promise in diminishing the effects of early dementia and proves a safe and effective method for treating acute migraine and PPA.
It is well documented that professional boxing causes neurological impairment. A new study reveals routine sparring can cause short term impairments in brain-muscle communication and a decrease in memory performance.
Expert pianists have altered mechanisms by with tactile and proprioceptive sensations suppress activity in the primary motor cortex.
Following a month of treatment with deep transcranial magnetic stimulation (dTMS), people with OCD reported a 45.2% reduction in symptom severity.
Researchers have identified the location of dysfunctional brain networks that lead to impaired sentence production and word-finding in primary progressive aphasia (PPA). PPA can occur in those with neurodegenerative diseases, such as frontotemporal dementia and Alzheimer's disease. Mapping the networks allows clinicians to apply non-invasive brain stimulation to potentially improve speech in those with PPA.
Imagination helps us act altruistically, a new study reports. When we see others in trouble, we imagine how we can help before acting. Researchers implicate the medial temporal lobe subsystem in guiding our prosocial behaviors.
