How are lesions used to study the brain?
Lesions allow the scientist to observe any loss of brain function that may occur. For instance, when an individual suffers a stroke, a blood clot deprives part of the brain of oxygen, killing the neurons in the area and rendering that area unable to process information.
What is a lesion study?
Lesion studies directly relate brain dysfunction — in the form of a lesion — to behavioral deficits. Similarly, manipulations of brain activity in NHPs or humans can be used to test causal predictions about relationships between brain activity and behavioral and cognitive symptoms in psychiatric populations [133, 134].
What are the advantages of a lesion study?
Lesion studies can provide strong tests of the necessary relationship between a brain structure and a psychological process, as well as providing a means to test whether processes are dissociable.
What is lesion and ablation?
The ablation lesion represents the tissue region that has undergone irreversible injury, and its quantification entails accurate assessment of the thermal dose received by the tissue.
What is lesion production?
Lesion Production. Destruction of a particular part of the brain. Lesions can be produced by passing electrical current (AC or DC) through an electrode or with chemicals (such as kainic acid or 6-hydroxydopamine) that destroy neurons.
Can stress cause brain lesions?
Psychological stress is linked to multiple sclerosis (MS) severity (e.g., to a heightened risk of brain lesion development).
Are brain lesions common?
