Aging is the biological process of declining physiologic function associated with increasing
mortality rate during advancing age. Humans and higher nonhuman primates exhibit …

During aging cognitive functions change differently from others. Unlike most of the body
systems, there is no clear decline pattern in cognitive processes. One of the most significant …

Background Spatial characterization of vertical organization of neurons in human cerebral
cortex, cortical columnarity or minicolumns, and its possible association with various …

We design and implement a small neural network, comprised of 52 fixed precision neurons-
computationally equivalent to a bounded memory Universal Turing Machine; this design is …

The brain is an extremely complex organ whose exploration and understanding requires the
use of several different in vivo approaches at multiple spatial and temporal ranges; one such …

The effects of normal aging in the brain can be characterized by mild impairments in memory
and executive function. The earliest of these impairments start developing in healthy people …

Astrocytes are the most numerous nonneuronal cell-type within the brain. These glial cells
support activities essential for neuronal function, regulating extracellular concentrations of …

Many areas of the human brain show intrinsic geometric order. This research focuses on
particular substructures called microcolumns, which are vertically oriented clusters of …
