An investigation into the synaptic conditions and celluar mechanisms underlying cerebellar synaptic plasticity
… postsynaptic currents. Brief raised frequency molecular layer stimulation produced a cAMP-dependent long-temi potentiation (LTP) of field potential (FP) responses (Salin et al., 1998). Thin slices of cerebellar vermis were prepared from 14-21 day old male Wistar rats decapitated under Halothane …

The interaction of ELKS with Ca2+ channel β subunits may contribute to active zone organization
… between ELKS1b and VDCC β4 at synapses in the molecular layer of the cerebellum, suggesting a synaptic role for the interaction of these two proteins. Analysis of a P/Q-type VDCC knockout mouse (Cacna1a-/-) revealed that the localization of the VDCC β4 subunit to the molecular layer was …

Modulation of GABAergic transmission in the cerebellar stellate cell network by neurotransmitter spillover and synaptic cross talk
… interconnected interneurons located in the outer molecular layer. They provide inhibition to Purkinje cells, thereby modulating the final output of the cerebellum. In this work, electrophysiological means were employed to study the stellate cell network at the single synapse level. Sustained …

Precursor phases in non-classical crystallization
… main objective of this thesis is to understand molecular crystallization as a multistep process with or without polymeric additives, including transient liquid-liquid phase separation, nanocrystal nucleation within the dense phase, and subsequent nanocrystal self-assembly or self-organization in …

Morphological Correlates Of Synaptic Plasticity After Long Term Potentiation In The Rat Hippocampus
… hemisphere of each animal and the inner molecular layer, where the medial perforant path has little synaptic input. Many previous studies of the first 6Omin post tetanisation have used high frequency stimulation (HFS) to induce LTP however, in this study – to determine whether changes in …

Two-dimensional materials for ubiquitous electronics
… The transport properties of exfoliated few layer flakes MoS2 and chemical vapor deposition (CVD) grown single layer large area MoS2 are systematically studies. Integrated devices and circuits based on large-scale single-layer MoS2 grown by CVD are demonstrated for the first time. The …

Structural and functional heterogeneity of cells in the rat hippocampus
… The dentate gyrus (DG) is the initial layer that receives and parses incoming signals. The signal is then transmitted to the CA3 and subsequently the CA1 layer. CA1 pyramidal neurons are the primary hippocampal projection neurons that provide a significant output pathway from the …

Active Micro-/Nano-Structures for Electromechanical Actuation
… as active nanoscale springs. An ensemble of such molecular springs takes the form of a self-assembled molecular layer sandwiched between ultra-smooth bottom electrodes and an active top nanoparticle contact. This nanoswitch operates by electromechanical modulation of the current tunneling through …

Molecular simulations of surfactants and silanes: Self-assembly in solutions and on surfaces, and friction between monolayers
… of stiction induced failure in MEMS. A detailed molecular level examination of the structure of these films is limited with the available experimental methods. Therefore, this work undertakes an investigation of the structure and properties of self-assembled alkylsilane monolayer films via Monte …
