A rapamycin-sensitive signaling pathway contributes to long-term synaptic plasticity in the hippocampus [PDF]

open access: yes, 2002
Many forms of long-lasting behavioral and synaptic plasticity require the synthesis of new proteins. For example, long-term potentiation (LTIP) that endures for more than an hour requires both transcription and translation.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Neuromorphic Light‐Responsive Organic Matter for in Materia Reservoir Computing

open access: yesAdvanced Materials, EarlyView.
In this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show

Flexible Selenium Nanowires with Tuneable Electronic Bandgaps

open access: yesAdvanced Materials, EarlyView.
Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent

Seizures, memory and synaptic plasticity

open access: yesSeizure, 1997
Electrophysiological studies of the rodent hippocampus show that repeated seizure activity has a profound, deleterious effect on an important form of synaptic plasticity (long-term potentiation, LTP) which has been suggested to underlie memory formation. It appears that seizure activity incrementally causes an indiscriminate and widespread induction of

A new stochastic STDP Rule in a neural Network Model

open access: yes, 2017
Thought to be responsible for memory, synaptic plasticity has been widely studied in the past few decades. One example of plasticity models is the popular Spike Timing Dependent Plasticity (STDP).

P3HT‐Based Electroactive Films for In Vitro Neuronal Cell Interfacing

open access: yesAdvanced Materials Interfaces, EarlyView.
Reducing the mechanical mismatch between bioelectronic devices and tissue is crucial for enhancing the characteristics of biointerfaces that better mimic the biological tissues. This work investigates the physico‐chemical properties of tunable nanostructured surfaces obtained from a blend of P3HT and MWCNT electroactive polymer.
