Cell-type specific innervation of cortical pyramidal cells at their apical dendrites
eLife, 2020 We investigated the synaptic innervation of apical dendrites of cortical pyramidal cells in a region between layers (L) 1 and 2 using 3-D electron microscopy applied to four cortical regions in mouse.

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Differential localization of glutamate receptor subunits at the drosophila neuromuscular junction [PDF]
, 2004 The subunit composition of postsynaptic neurotransmitter receptors is a key determinant of synaptic physiology. Two glutamate receptor subunits, Drosophila glutamate receptor IIA (DGluRIIA) and DGluRIIB, are expressed at the Drosophila neuromuscular ...

RNA, 2015 One reason we learn and remember is because synapses, the places where axons and dendrites meet, undergo experience-dependent changes whose long-lasting nature may underlie the formation and persistence of memory. Indeed, neurons use these morphological and biochemical alterations to distinguish experienced (i.e., stimulated) from naive (unstimulated ...

Advanced Functional Materials, EarlyView.Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

New ways of looking at synapses [PDF]
, 2007 Current concepts of synaptic fine-structure are derived from electron microscopic studies of tissue fixed by chemical fixation using aldehydes. However, chemical fixation with glutaraldehyde and paraformaldehyde and subsequent dehydration in ethanol ...

Dark microglia: Why are they dark?
Communicative & Integrative Biology, 2016 Using transmission electron microscopy (TEM) we recently characterized a microglial phenotype that is induced by chronic stress, fractalkine receptor deficiency, aging, or Alzheimer disease pathology.

Glycobiology of the synapse [PDF]
Glycobiology, 2002 Synapses are the fundamental units of connectivity that link together the nervous system. Lectin studies from 30 years ago suggested that specific glycans are concentrated at neuromuscular synapses in the peripheral nervous system and at excitatory synapses in the brain.
