Higher Brain Neurons Succumb to Acute Stroke-Like Insult While Lower Brain Neurons Strongly Resist
Pyramidal neurons (PyNs) in ‘higher’ brain are highly susceptible to acute stroke injury yet ‘lower’ brain regions better survive global ischemia, presumably because of better residual blood flow. Here we show that projection neurons in ‘lower’ brain regions of hypothalamus and brainstem …

Activity and Structure of Auditory Brain Neurons Underlying Phonotactic Behaviour in Female Crickets
… and coincidence detector circuit with five neurons underlying auditory pattern recognition in the bi-spotted cricket Gryllus bimaculatus was identified by Schöneich et al (2015). My results here confirmed the morphology of the five identified neurons. Moreover, the group labeling of the …

Glutamate regulates neurite outgrowth of descending neurons in culture from larval lamprey
… cord-transected larval lamprey, descending brain neurons, most of which are reticulospinal (RS) neurons, regenerate their axons across a transection site and contribute to behavioral recovery. In the present study, DiI-labeled descending brain neurons in larval lamprey were dissociated and …

Optimizing Multi-Well Micro-Electrode Array (MW-MEA) Design to Study the Electrophysiology of Neurons
… performed on the second MEA design, using snail brain neurons. Snail brain neurons were used to limit the complexity of neuronal recordings and to be able to focus the analysis on the electrode characteristics. However, due to the COVID-19 related shutdown, the snail recording could not be …

Neuroscience and Galen: Body, Selfhood and the Materiality of Emotions on the Early Modern Stage
… body nor the theory of the material chemical brain can provide a stable explanation for emotional experiences. Instead, both the early modern writers and my contemporaries weave together "dualistic habits of thought" and the monistic, materialistic language (of either Galenic humoralism or …

Differential Na+/K+ Pump Isoform Expression in Higher and Lower Brain Regions of the Mouse
… clinically and experimentally that the higher brain is highly vulnerable to ischemia, while the lower brain is comparatively resilient. Discovering how lower brain neurons naturally resist ischemic stress may help to design new strategies for improving higher brain survival following ischemia. …

Regulation of SNARE-Mediated Synaptic Vesicle Release by Synaptotagmins and Complexins
In the brain, neurons communicate with each other by synaptic transmission. This process includes release of neurotransmitter from vesicles in the presynaptic neuron into the synaptic cleft, and sensing of these neurotransmitters by the postsynaptic neuron with specific receptors. Long-lasting …

Role of the Neurotransmitter Glutamate in Neural Stem and Progenitor Cells Differentiation into Oligodendrocytes
Various regions of the mammalian brain, including the subventricular zones (SVZs) of the hippocampus and the dentate gyrus (DG), contain niches of undifferentiated neural stem and progenitor cells (NSPCs) which persist from development, all throughout adulthood. These cells can differentiate into …

Manipulations of spike trains and their impact on synchrony analysis
… be identified as the computing mechanism of the brain. Neurons are complex cells that do not operate in isolation, but they are organized in a highly connected network structure. There is experimental evidence that groups of neurons dynamically synchronize their activity and process brain …

Mechanisms of Hypoxia-Induced Neurovascular Remodeling in PlGF Knockout Mice
… and low capacity for energy storage of the brain, neurons are vitally reliant on a constant oxygen supply. Under chronic mild hypoxic conditions (10% oxygen), angiogenesis is induced in the brain in an attempt to restore tissue oxygen tension to normal levels. In brain hypoxia, vascular …

Interaction Mapping of the Atypical Protein Kinase WNK3
… various Cl- transporting epithelia and certain brain neurons with GABA-A ionotropic receptors. My goal with these interaction mapping efforts has been to build a collection of putative WNK3 interactors to serve as a source of information and project leads for the ongoing research program of the …

New Way of Generating Electromagnetic Waves Using Permanent Magnet
… and ULF electromagnetic (EM) waves for studying brain function and treating neurological conditions. The main challenge is that most VLF and ULF generators are large and power-hungry, making them impractical to use in many applications. As a result, recent approaches using permanent magnets have …

Topological organization of the trigeminal system in the lamprey and restoration following axonal regeneration

Growing Up POMC: Pro-opiomelanocortin in the Developing Brain
Neurons in the arcuate nucleus of the hypothalamus (ARH) play a central role in the regulation of body weight and energy homeostasis. ARH neurons directly sense nutrient and hormonal signals of energy availability from the periphery and relay this information to secondary nuclei targets, where …
