For half a century, the human brain was believed to contain about 100 billion neurons and
one trillion glial cells, with a glia: neuron ratio of 10: 1. A new counting method, the isotropic …

Biological nonassociative learning is one of the simplest forms of unsupervised learning in
animals and can be categorized into habituation and sensitization according to mechanism …

The cellular composition of brains shows largely conserved, gradual evolutionary trends
between species. In the primate spinal cord, however, the glia–neuron ratio was reported to …

Biologic scaffolds composed of mammalian extracellular matrix (ECM) promote constructive
remodeling of tissues via mechanisms that include the recruitment of endogenous …

A laskan H usky encephalopathy (AHE 1) is a fatal brain disease associated with a mutation
in SLC19A3. 1 (c. 624insTTGC, c. 625C> A). This gene encodes for a thiamine transporter 2 …

Objective—To determine thiamine-dependent enzyme activities in various tissue samples of
Pacific harbor seals (Phoca vitulina) and thiaminase activities in dietary fish. Design—Cross …

Non‐associative learning plays an important role in the biological and cognitive systems
and is one of the important pathways for unsupervised learning in biology. The proposed …

Associative learning and memory are widely studied, but non associative learning is rarely
discussed. A non associative learning circuit based on memristor is proposed in this paper …

Human childhood and adolescence is the period in which adult cognitive competences
(including those that create the unique cooperativeness of humans) are acquired. It is also a …
