platform_img_21.jpeg

Analysis technique

Whole-cell patch clamp recording

Available disease models

Brain slice

Somatosensory thalamocortical circuit (thalamus - barrel cortex)
Cognition / Memory circuit (hippocampus; Schaffer collateral – CA1)
Cognition / Learning and memory circuit (hippocampus; dentate gyrus – CA3)
Motivation / Voluntary movement circuit
(Huntington’s disease; prefrontal cortex– striatum)
Reward circuit (mPFC - nucleus accumbens)

 

Spinal cord slice

Pain excitatory circuit (primary afferent - substantia gelatinosa)
Pain inhibitory circuit (GABA_A current)

Available analyses

  • Analysis of evoked EPSP (excitatory post-synaptic potential) and IPSP (inhibitory post-synaptic potential) at specific neuronal circuits

  • Measurement and analysis of miniature EPSP at specific types of neurons

  • Analysis of synaptic plasticity by measuring LTP (long-term potentiation), LTD (long-term depression), Input-output curve and Paired pulse ratio etc

Examples

Evaluation of drug efficacy on synaptic function by measuring EPSCs at Schaffer collateral - CA1 circuit from acute hippocampal slices in Alzheimer’s disease animal model
