Tergic mixed synapse,possibly involving a spiny interneuron or a CApyr dendrite within the infrapyramidal bundle. These data demonstrate widespread distribution of neuronal gap junctions in hippocampus,with most either at glutamatergic mixed synapses or in association with extrasynaptic glutamate receptor clusters. We also demonstrated dyecoupling of CApyrtoMF axons in weakly fixed hippocampal slices,extending prior dyecoupling information also obtained utilizing LY. These information give direct anatomical evidence supporting our current functional evidence for glutamatergic transmission from dentate granule cells to CApyr (Vivar et al,but much more commonly supply proof for widespread glutamatergic mixed synapses throughout the hippocampal formation.

Uchigashima et al and nitric oxide (Nicolarakis et al. The distinctive subregions of the hippocampus must be finetuned as a way to sustain a appropriate excitatoryinhibitory balance; and interregional manage of excitability (by speedy electrical transmission) may be a mechanism that enables synchrony in pattern transmission. Among the big consequences in the disruption of such balance may be the emergence of epileptic activity. In humans,seizures of focal origin specifically complex partial seizures have a propensity to originate in temporal lobe structures,which includes hippocampus,entorhinal cortex,and nearby regions,with seizure activity arising within the temporal lobe entering the hippocampus through the perforant path from the entorhinal cortex. Noteworthy,the CA region plays a vital part inside the generation of oscillatory activity and within the generation and propagation of seizures (Traub et al,and gap junction channels are strongly modulated by alterations that epileptiform activity produces within the microenvironment (Traub et al.Frontiers in Neuroanatomywww.frontiersin.orgMay Volume Short article HamzeiSichani et al.Glutamatergic mixed synapses in hippocampus
