Reconnection means creation of an entirely new connection or the elimination of an old one.
We view the loss of proximal SAC SAC connections as synapse elimination, a process that occurs in many and perhaps most neuronal types (Kano and Hashimoto, 2009) but has not previously been described for SACs.
The authors show with very precise lesions that when the MB (reciprocal) connections with the ventral tegmental nucleus of Gudden (VTNg) or the connections of the ascending mammillothalamic tract (MMT) to the anterior thalamus are eliminated, large deficits in spatial memory occur while, in contrast, elimination of connections provided by the postcommissural fornix (PCF) have little effect.
Underused connections are later eliminated, and this elimination process, called synaptic pruning, is highly dependent upon experience.
Schizophrenia is known to have a genetic component but the research, published online in Nature on Wednesday, links the disease with specific gene variants and a biological process called synaptic pruning - the elimination of connections between neurons, or brain cells.
After P10, as electrical synapses approach the time point of their elimination, disynaptic connections between VBN neurons begin to emerge, illustrating a sequential developmental time course for the 2 types of connections (Lee et al. 2010).
The role of Lis1 in the regulation of proper formation and elimination of connections between neurons is an important new avenue for investigation of mechanisms contributing to neurobehavioural disorders in which altered socialization is a prominent component.
Ho hoped that the category's elimination would eliminate the "craziness " surrounding the Hawaiian music controversy (he and Carrere were accused of lacking appreciation for Hawaiian music and for having inside connections to the music industry for residing in Los Angeles).
The connection between model-completeness and elimination of quantifiers is as follows.
This synaptic revision corresponds to the elimination of redundant connections and to the establishment of functional connectivities.
