The gradient clusteron: A model neuron that learns to solve classification tasks via dendritic nonlinearities, structural plasticity, and gradient descent.
TL;DR: In this paper, a gradient clusteron (G-clusteron) is proposed to solve the XOR problem from arbitrary initial conditions, where synapses are attracted to or repelled from each other in an input-and location-dependent manner.

Machines Learning - Towards a New Synthetic Autobiographical Memory
TL;DR: This position paper highlights desiderata for a modern implementation of synthetic autobiographical memory based on human episodic memory, and proposes that a recently developed model of hippocampal memory could be extended as a generalised model of autobiographies memory.
Journal ArticleDOI
In for a penny, in for a pound: examining motivated memory through the lens of retrieved context models.
TL;DR: For example, this paper found that when people encounter items that they believe will help them gain reward, they later remember them better than others, and that these effects would be stronger when stimuli that predict high and low reward can compete with each other during both encoding and retrieval.

Prediction errors during naturalistic events modulate hippocampal representations and drive episodic memory updating

TL;DR: It is concluded that prediction errors during memory reactivation prompt the hippocampus to abandon ongoing predictions and neural representations following prediction error, and the hippocampus switches to an externally-oriented processing mode that supports memory updating.

Game Mechanics Matter: Differences in Video Game Conditions Influence Memory Performance
TL;DR: Behavioral evidence indicates that participants who played in the video game conditions with clear reward mechanisms performed better on a declarative memory task than those who played without reward mechanisms, suggesting that gaming might have short-term and long-term effects on the hippocampus.

The Organization of Behavior: A Neuropsychological Theory
TL;DR: In this paper, the authors discuss the first stage of perception: growth of the assembly, the phase sequence, and the problem of Motivational Drift, which is the line of attack.

An Integrative Theory of Locus Coeruleus-Norepinephrine Function: Adaptive Gain and Optimal Performance.
TL;DR: In this article, the locus coeruleus-norepinephrine (LC-NE) system plays a more complex and specific role in the control of behavior than investigators previously thought.

Depth of processing and the retention of words in episodic memory.

TL;DR: For instance, Craik and Lockhart as discussed by the authors explored the levels of processing framework for human memory research and found that deeper encodings took longer to accomplish and were associated with higher levels of performance on the subsequent memory test.
