Lateral entorhinal cortex is necessary for associative but not nonassociative recognition memory [PDF]

open access: yes, 2013
This work was supported by BBSRC [Grant number BB/I019367/1]The lateral entorhinal cortex (LEC) provides one of the two major input pathways to the hippocampus and has been suggested to process the nonspatial contextual details of episodic memory ...

Associative memory cells and their working principle in the brain [version 1; referees: 2 approved]

open access: yesF1000Research, 2018
The acquisition, integration and storage of exogenous associated signals are termed as associative learning and memory. The consequences and processes of associative thinking and logical reasoning based on these stored exogenous signals can be memorized ...

NEURAL NETWORK-BASED METHODS FOR FINDING THE SHORTEST PATH and establishing associative connections between objects

open access: yesРадіоелектронні і комп'ютерні системи, 2023
Nowadays, solving optimizations problems is one of the tasks for intelligent computer systems. Currently, there is a problem of insufficient efficiency of optimizations tasks solving methods (for example, high computing time and/or accuracy).

Critical role of the cholinergic system for object-in-place associative recognition memory [PDF]

open access: yes, 2009
Object-in-place memory, which relies on the formation of associations between an object and the place in which it was encountered, depends upon a neural circuit comprising the perirhinal (PRH) and medial prefrontal (mPFC) cortices.

Do intensive studies of a foreign language improve associative memory performance?

open access: yesFrontiers in Psychology, 2011
Formal education has been proposed to shape life-long cognitive development. Studies reporting that gains from cognitive training transfer to untrained tasks suggest direct effects of mental activity on cognitive processing efficiency.

The Effects of Goal Relevance and Perceptual Features on Emotional Items and Associative Memory

open access: yesFrontiers in Psychology, 2017
Showing an emotional item in a neutral background scene often leads to enhanced memory for the emotional item and impaired associative memory for background details.

Medial temporal lobe contributions to intra-item associative recognition memory in the ageing brain

open access: yesFrontiers in Behavioral Neuroscience, 2014
Ageing is associated with a decline in episodic memory function. This is accompanied by degradation of and functional changes in the medial temporal lobe (MTL) which subserves mnemonic processing.

The importance of the ventromedial prefrontal cortex for associative memory in older adults: A latent structural equation analysis

open access: yesNeuroImage, 2020
Older adults show relatively minor age-related decline in memory for single items, while their memory for associations is markedly reduced. Inter-individual differences in memory function in older adults are substantial but the neurobiological ...

Nicotinic Acetylcholine Receptors Control Encoding and Retrieval of Associative Recognition Memory through Plasticity in the Medial Prefrontal Cortex

open access: yesCell Reports, 2018
Summary: Nicotinic acetylcholine receptors (nAChRs) expressed in the medial prefrontal cortex have critical roles in cognitive function. However, whether nAChRs are required for associative recognition memory and the mechanisms by which nAChRs may ...

Associative Memory Extinction Is Accompanied by Decayed Plasticity at Motor Cortical Neurons and Persistent Plasticity at Sensory Cortical Neurons

open access: yesFrontiers in Cellular Neuroscience, 2017
Associative memory is essential for cognition, in which associative memory cells and their plasticity presumably play important roles. The mechanism underlying associative memory extinction vs.
