Elucidating the role of neuron-astrocyte metabolic coupling in learning and memory

The brain has very high energy demands that are mainly met by the circulating blood glucose to ensure its proper functioning. Thus, it is not surprising that though the human brain weighs only 2- 3% of the body weight, it consumes approximately 25% of tota ...

Ammonia toxicity to the brain

Cristina Ramona Cudalbu

Hyperammonemia can be caused by various acquired or inherited disorders such as urea cycle defects. The brain is much more susceptible to the deleterious effects of ammonium in childhood than in adulthood. Hyperammonemia provokes irreversible damage to the ...

Altered Synaptic Dynamics during Normal Brain Aging

Graham Knott, Bohumil Maco

What is the neuroanatomical basis for the decline in brain function that occurs during normal aging? Previous postmortem studies have blamed it on a reduction in spine density, though results remain controversial and spine dynamics were not assessed. We us ...

Robo3-Driven Axon Midline Crossing Conditions Functional Maturation of a Large Commissural Synapse

Ralf Schneggenburger, Zsolt Norbert Babai

During the formation of neuronal circuits, axon pathfinding decisions specify the location of synapses on the correct brain side and in correct target areas. We investigated a possible link between axon midline crossing and the subsequent development of ou ...

Sensing Acetylcholine and Anticholinesterase Compounds

Kai Johnsson, Alberto Schena

Acetylcholine is a key neurotransmitter, and anticholinesterase agents are essential compounds used as medical drugs, pesticides, and chemical warfare agents. A semisynthetic fluorescence-based probe for the direct, real-time detection of acetylcholine and ...

A Semisynthetic Fluorescent Sensor Protein for Glutamate

Kai Johnsson, Luc Reymond, Rudolf Griss, Matthias Albert Brun, Kui Thong Tan

We report the semisynthesis of a fluorescent glutamate sensor protein on cell surfaces. Sensor excitation at 547 nm yields a glutamate-dependent emission spectrum between 550 and 700 nm that can be exploited for ratiometric sensing. On cells, the sensor di ...

Lentiviral Transgenesis as a Tool to Study the Role of Uncoupling Protein Isoforms in the Nervous System

Hélène Danielle Perreten Lambert

A tight coupling exists between synaptic activity and glucose utilization by astrocytes. Metabolic cooperation between neurons and astrocytes mediates this coupling. During synaptic activation, glutamate that is released in the synaptic cleft as a neurotra ...

Relationship between physiological measures of excitability and levels of glutamate and GABA in the human motor cortex

Magnetic resonance spectroscopy (MRS) allows measurement of neurotransmitter concentrations within a region of interest in the brain. Inter-individual variation in MRS-measured GABA levels have been related to variation in task performance in a number of r ...

Simultaneous neurochemical stimulation and recording using an assembly of biosensor silicon microprobes and SU-8 microinjectors

Nico de Rooij, Peter Van der Wal, Olivier Frey

In this contribution we present multi-channel microinjector arrays fabricated by a reliable three-layer SU-8 process for the local delivery of specific substances into brain tissue. They are designed to be assembled with previously developed. implantable b ...

RIM Determines Ca²+ Channel Density and Vesicle Docking at the Presynaptic Active Zone

Yunyun Han

Fast neurotransmitter release is essential for neuron-neuron communication and is initiated by the opening of voltage-gated Ca2+ channels close to docked vesicles at the presynaptic active zone. The high concentration of Ca2+ channels at the active zone is ...
