Human Neuroanatomy

Nonlinear associations between human values and neuroanatomy.

Human values guide behavior and the smooth functioning of societies. Schwartz's circumplex model of values predicts a sinusoidal waveform in relations between ratings of the importance of diverse human value types (e.g., achievement, benevolence) and any variables psychologically relevant to them. In this neuroimaging study, we examined these nonlinear associations between values types and brai...

Neuroanatomy of the human hypothalamic kisspeptin system.

Hypothalamic kisspeptin (KP) neurons are key players in the neuronal network that regulates the onset of puberty and the pulsatile secretion of gonadotropin-releasing hormone (GnRH). In various mammalian species, the majority of KP-synthesizing neurons are concentrated in two distinct cell populations in the preoptic region and the arcuate nucleus (ARC). While studies of female rodents have pro...

Functional Neuroanatomy: The Locus of Human Intelligence

A new study mapping the functional effects of brain lesions has revealed a surprising map of human intelligence, stimulating a re-evaluation of data from purely correlative methods such as functional magnetic resonance imaging.

Functional neuroanatomy of human slow wave sleep.

The distribution of regional cerebral blood flow (rCBF) was estimated during sleep and wakefulness by using H215O positron emission tomography (PET) and statistical parametric mapping. A group analysis on 11 good sleepers (8 with steady slow wave sleep, SWS) showed a significant negative correlation between the occurrence of SWS and rCBF in dorsal pons and mesencephalon, thalami, basal ganglia,...
