چکیده
The basal forebrain complex (BFC) is a small but intricate structure. Its organization and function is hard to investigate using conventional methods, especially in humans. By combining new methods of research we present a comprehensive overview of this complex, in order to better understand its function in normal and diseased brains. Methods: The right and left BFC of a 29-year-old male were reconstructed from gallcocyanin (Nissl) stained 440 μm-thick serial horizontal sections by using advanced computer-assisted 3D reconstruction software. Results: The reconstructed components in the present case include Ch2, Ch3, Ch4am-al, Ch4i, Ch4p, juxtacommissural, Ayala’s medial (subpallidal) and lateral (periputaminal) subnuclei. These components are arranged in an arch-like course mainly beneath the anterior commissure. The bilateral volume of all subnuclei was 99.06 mm3, the left side accounting for 48.05 mm3. Some of the subnuclei exhibited volume asymmetry indices varying from 28.3 to 12.9%.The volume of Ayalas’ lateral or periputaminal nucleus was 9.7% higher on the right, than on the left side. Conclusions: Our methodological approach promises to be highly effi cient and reproducible in studying morphofunctional correlations in complex cognitive features

Cases of “adolescent insanity” were known to Kraepelin’s forerunners and lay at the core of his concept of dementia præcox. In the post-neuroleptic era it became clear that dementia may also occur in schizophrenia as a fully reversible state depending on psychopathological status. In the present review we discuss the validity of applying the concept of dementia to schizophrenia. We concur with ...

The colorectal cancer ranks high among the malignant tumours in incidence and mortality and irinotecan is standardly used in palliative treatment of metastatic disease in every therapeutic line. Unfortunately, the treatment with irinotecan is often associated with severe toxicities, especially neutropenia and diarrhea. The majority of the toxic manifestation is caused by the insufficient deacti...
