Dendritic Signal Integration
... Each granule cell receives on average only four excitatory inputs, each made onto a very short dendrite. Because the dendrites are so short, their influence on synaptic integration is minimal. This also offers technical advantages for studying synaptic physiology with patch-clamp recordings from the ...

Sensory periphery input is detected and selected basing on single neuron intrinsic resonance frequency characteristics. Input frequency preference can be dynamically tuned by biasing the membrane conductance and potential. ...
