Demonstrating Advantages of Neuromorphic Computation: A Pilot Study [PDF]

, 2019
Neuromorphic devices represent an attempt to mimic aspects of the brain's architecture and dynamics with the aim of replicating its hallmark functional capabilities in terms of computational power, robust learning and energy efficiency.

Diverse processing of pharmacological and natural rewards by the central amygdala

Cell Reports, 2023
Summary: The central amygdala (CeA) with its medial (CeM) and lateral (CeL) nuclei is the brain hub for processing stimuli with emotional context. CeL nucleus gives a strong inhibitory input to the CeM, and this local circuitry assigns values (positive ...

Psychedelics Promote Structural and Functional Neural Plasticity. [PDF]

, 2018
Atrophy of neurons in the prefrontal cortex (PFC) plays a key role in the pathophysiology of depression and related disorders. The ability to promote both structural and functional plasticity in the PFC has been hypothesized to underlie the fast ...

Olfactory bulb plasticity ensures proper olfaction after severe impairment in postnatal neurogenesis

Scientific Reports, 2017
The olfactory bulb (OB) neurons establish a complex network that ensures the correct processing of the olfactory inputs. Moreover, the OB presents a lifelong addition of new neurons into its existing circuitry.

Neuronal assembly dynamics in supervised and unsupervised learning scenarios [PDF]

, 2013
The dynamic formation of groups of neurons—neuronal assemblies—is believed to mediate cognitive phenomena at many levels, but their detailed operation and mechanisms of interaction are still to be uncovered.

Reinforcement learning in populations of spiking neurons [PDF]

, 2008
Population coding is widely regarded as a key mechanism for achieving reliable behavioral responses in the face of neuronal variability. But in standard reinforcement learning a flip-side becomes apparent.

Birdsongs alleviate anxiety and paranoia in healthy participants

Scientific Reports, 2022
The present study investigated the effect of urban (traffic noise) vs. natural (birdsongs) soundscapes on mood, state paranoia, and cognitive performance, hypothesizing that birdsongs lead to significant improvements in these outcomes. An additional goal

Neuronal Plasticity and Function

Clinical Neuropharmacology, 1993
Neuronal plasticity is a key issue in neuroscience. It is defined as the capability of the neuron to adapt to a changing internal or external environment, to previous experience or to trauma. It appears that during all phases of the individual life span in the nervous system, changes take place that relate to development, degeneration, and regeneration.

Click Chemistry (CuAAC) and Detection of Tagged de novo Synthesized Proteins in Drosophila

Bio-Protocol, 2019
Copper-catalyzed azide-alkyne-cycloaddition (CuAAC), also known as ‘click chemistry’ serves as a technique for bio-orthogonal, that is, bio-compatible labeling of macromolecules including proteins or lipids.
