The authors report on and discuss the historical evolution of the 3 intellectual and scientific domains essential for the current understanding of the function of the human thalamus: 1) the identification of the thalamus as a distinct anatomical and functional entity, 2) the subdivision of thalamic gray matter into functionally homogeneous units (the thalamic nuclei) and relative disputes Cited by: 1. 2.

However, compared to the previous studies, striatal lesions appear to induce the greatest degree of impairment of any structure examined so far, e.g., in the Duffy et al. study, hippocampal lesions resulted in an average of approximately 5–6 errors during the final trial block, indicating significant acquisition, while in the current study.
The volume of lesions was quantified at the start of the study and patients received yearly scans on the same 3 Tesla MRI machine for more than five years. Lesion volumes were calculated over the five years of the study. In the year study, the researchers conducted analyses at the Center for Biomedical Imaging in the CTSI and at the BNAC.

Corpus Striatum is either of two gray and white, striated bodies of nerve fibers located in the lower lateral wall of each cerebral Striatum is a striped mass of white and grey matter located in front of the thalamus in each cerebral hemisphere; consists of the caudate nucleus and the lenticular nucleus.
Lesions of dorsolateral striatum preserve outcome expectancy but disrupt habit formation in instrumental learning Article (PDF Available) in European Journal of Neuroscience 19(1) A case report described how lesions of the dorsal striatum (caudate and putamen) dramatically reduced OCD symptoms (Lambrecq et al., ).
Biochemical studies have shown higher dopamine. In the present study we hypothesized that lesions of the striatum would disrupt acquisition in the unit T-maze. In addition, we were also interested in evaluating the potential differential contributions of the medial and lateral striatal subregions on performance in the unit T-maze, as has been observed in the water maze.

Alzheimer’s disease (AD) has been described as an irreversible, neurodegenerative brain disease and generally affects gray matter. Nevertheless, several researchers have revealed that AD is also associated with white matter pathology 1, corpus callosum (CC), as the largest interconnecting white matter tract in the brain, may inevitably be affected by by: The study classified small lesions as those with diameters less than mm.
Lesions larger than that are probably considered moderate. (On another site I read that the "average" brain lesion is .wallerian degeneration: [ de-gen″ĕ-ra´shun ] deterioration; change from a higher to a lower form, especially change of tissue to a lower or less functionally active form.
When there is chemical change of the tissue itself, it is true degeneration; when the change consists in the deposit of abnormal matter in the tissues, it is infiltration.
