Encoding and decoding in parietal cortex during sensorimotor decision-making
TLDR
This work examined the neural code in LIP at the level of individual spike trains using a statistical approach based on generalized linear models and derived an optimal decoder for heterogeneous, multiplexed LIP responses that could be implemented in biologically plausible circuits.
Single-trial spike trains in parietal cortex reveal discrete steps during decision-making
TLDR
Examination of single-trial responses in LIP using statistical methods for fitting and comparing latent dynamical spike-train models found that choice-selective neurons were better described by the stepping model, and the inferred steps carried more information about the animal’s choice than spike counts.
Getting directions from the hippocampus: The neural connection between looking and memory
Signal Multiplexing and Single-Neuron Computations in Lateral Intraparietal Area During Decision-Making
TLDR
Recording single neuron spiking activity in LIP during a well-studied moving-dot direction–discrimination task and manipulating whether a saccade target was present in the RF during decision-making shows that cells multiplex decision signals with decision-irrelevant visual signals.
A temporal record of the past with a spectrum of time constants in the monkey entorhinal cortex
TLDR
It is suggested that the primate entorhinal cortex uses a spectrum of time constants to construct a temporal record of the past in support of episodic memory.
Response to Comment on “Single-trial spike trains in parietal cortex reveal discrete steps during decision-making”
TLDR
It is found that stepping dynamics provided a better statistical description of lateral intraparietal area spike trains than diffusion-to-bound dynamics for a majority of neurons.
Neurons in Primate Entorhinal Cortex Represent Gaze Position in Multiple Spatial Reference Frames
TLDR
It is reported that spatial entorhinal neurons are widespread in the monkey and these neurons are capable of showing a world-based spatial reference frame locked to the bounds of explored images.
Neural correlates and neural computations in posterior parietal cortex during perceptual decision-making
TLDR
These issues motivate the adoption of a more general “encoding-decoding framework” that will be fruitful for more detailed contemplation of how neural computations in LIP relate to the formation of perceptual decisions.
A temporal record of the past with a spectrum of time constants in the monkey entorhinal cortex
TLDR
Taken together, these findings suggest that the primate entorhinal cortex uses a spectrum of time constants to construct a temporal record of the past in support of episodic memory.
