Propagation of Epileptiform Activity Can Be Independent of Synaptic Transmission, Gap Junctions, or Diffusion and Is Consistent with Electrical Field Transmission

Journal of Neuroscience, 2014
The propagation of activity in neural tissue is generally associated with synaptic transmission, but epileptiform activity in the hippocampus can propagate with or without synaptic transmission at a speed of ∼0.1 m/s.

Neuromorphic Light‐Responsive Organic Matter for in Materia Reservoir Computing

Advanced Materials, EarlyView.
In this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show

Achieving High-Frequency Optical Control of Synaptic Transmission

Journal of Neuroscience, 2014
The optogenetic tool channelrhodopsin-2 (ChR2) is widely used to excite neurons to study neural circuits. Previous optogenetic studies of synapses suggest that light-evoked synaptic responses often exhibit artificial synaptic depression, which has been ...

Frequency Switching Neuristor for Realizing Intrinsic Plasticity and Enabling Robust Neuromorphic Computing

Advanced Materials, EarlyView.
A frequency switching (FS) neuristor is proposed, comprising a Mott memristor and a valence change mechanism (VCM) memristor. The FS neuristor exhibits a multi‐level frequency–voltage (f–V) characteristics, enabling the implementation of neuronal intrinsic plasticity transfer functions.

Revisiting Ferroelectric‐Gated Phototransistors: A Tripartite Synapse‐Inspired Approach to In‐Sensor Image Processing

Advanced Materials, EarlyView.
A ferroelectric‐gated phototransistor (FGPT) enables linear and multilevel modulation of photoconductance through partial polarization switching and photogating effects. The device achieves photonic non‐volatility over a 153 dB dynamic range and performs in‐sensor processing under unstructured illumination, demonstrating enhanced face recognition ...
