We conducted an event-related, functional MRI investigation of 12 male's and 12 female's reasoning about conditional deontic rules, rules regulating people's behavior. We employed two different types of rules: social contracts and nonsocial, precautionary rules. Although the rules and the demands of the task were matched in terms of their logical structure, reasoning about social contracts and ...

In mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus is considered as the master circadian pacemaker. In this paper, we analyze the special structure of SCN from mathematical viewpoint in an analytical way. We show how the special structure of the SCN is exploited in synchronization in an analytical way, i.e., why the ventrolateral (VL) part has fewer but compactly connected neuron...

HGPPS is a rare congenital disorder resulting from cranial nuclear maldevelopment and characterized by absence of conjugate horizontal eye movements, preservation of vertical gaze & convergence, progressive scoliosis developing in childhood and hypoplasia of dorsomedial brainstem structures associated with sagittal cleft of pons and medulla. We present a 19 years old male, with restriction of e...

Simultaneous recordings of the left and right crus IIA of the cerebellar cortex in the rat have demonstrated that Purkinje cells of both sides can be activated synchronously by their climbing fibers. Because climbing fibers arise exclusively from the contralateral inferior olive (IO), this physiological finding seems to contradict the anatomy. To define the structural basis responsible for the ...
