Spatial modulation of visual responses arises in cortex with active navigation [PDF]
eLife, 2021 During navigation, the visual responses of neurons in mouse primary visual cortex (V1) are modulated by the animal’s spatial position. Here we show that this spatial modulation is similarly present across multiple higher visual areas but negligible in ...

Spatial modulation of hippocampal activity in freely moving macaques. [PDF]
Neuron, 2021 Summary The hippocampal formation is linked to spatial navigation, but there is little corroboration from freely-moving primates with concurrent monitoring of head and gaze stances.

Optimized Design of Distributed Quasi-Cyclic LDPC Coded Spatial Modulation [PDF]
Sensors, 2023 We propose a distributed quasi-cyclic low-density parity-check (QC-LDPC) coded spatial modulation (D-QC-LDPCC-SM) scheme with source, relay and destination nodes. At the source and relay, two distinct QC-LDPC codes are used.
