Science is showing how the brain's development affects free will | Philadelphia Inquirer | 01/08/2012A baseball player, for example, "sees the ball and hits the ball" without waiting to think about it. The batter has practiced recognizing the pitch and timing the swing until lower nerve centers govern the process. Similarly, a skilled pianist is able to perform complex compositions on the keys while carrying on a conversation or planning a dinner. The individual brain forms many such connections through thousands of hours of practice; other modules have developed in the brain of the species over millions of years of evolution. Therefore, we jump when something is slithering in the nearby grass, even those of us who have never seen a snake; moreover, we share this innate response with other primates on the same basis.
Molecular and Cellular Neuroscience : A transcriptomic analysis of type I-III neurons in the bed nucleus of the stria terminalisThe activity of neurons in the anterolateral cell group of the bed nucleus of the stria terminalis (BNST ALG ) plays a critical role in anxiety- and stress-related behaviors. Histochemical studies have suggested that multiple distinct neuronal phenotypes exist in the BNST ALG . Consistent with this observation, the physiological properties of BNST ALG neurons are also heterogeneous, and three distinct cell types can be defined (Types I–III) based primarily on their expression of four key membrane currents, namely I h , I A , I T , and I K(IR) . Significantly, all four channels are multimeric proteins and can comprise of more than one pore-forming α subunit. Hence, differential expression of α subunits may further diversify the neuronal population. However, nothing is known about the relative expression of these ion channel α subunits in BNST ALG neurons.
all matter is merely energy condesnsed into a slow vibration, experiencing itself subjectively. there is no death, life is only a dream and we are the imagination of ourselves......here's tom with the weather by Feb 13
Stories of "broken brains" like this are fascinating. I highly recommend the book "The Man Who Mistook His Wife for a Hat" by Oliver Sacks. by Jan 24
