Paired Deep Brain Stimuli Elicit Short-Term Facilitation in Globus Pallidus Interna and Subthalamic Nucleus. [PDF]
Mov DisordAbstract Background Deep brain stimulation (DBS) elicits oscillatory local field potentials in patients with Parkinson's disease (PD) and other movement disorders. Greater knowledge about the fast dynamics of these neural responses could shed light on circuit pathophysiology and inform novel approaches to neuromodulation therapies.

Progress in cancer neuroscience
MedComm, Volume 4, Issue 6, December 2023., 2023 Neurons and cancer cells’ synaptic communication can modulate cancer growth via neurotransmitters and voltage‐mediated mechanisms. Besides, paracrine signaling between cancer and nerve cells, for instance, the neuron‐mediated secretion of growth factors or neurotransmitters, modulates cancer growth in various tissues.

Advanced Science, Volume 10, Issue 22, August 4, 2023., 2023 Spontaneous threshold lowering (STL) originates from the intrinsic neuronal plasticity observed in biological neurons, which plays an important role in a number of learning protocols like spatial attention. Here for the first time artificial STL neurons using second‐order yttria‐stabilized zirconia with Ag doping (YSZ:Ag) memristors at a small hardware

Human Brain Mapping, Volume 44, Issue 6, Page 2654-2663, April 15, 2023., 2023 Here we investigated seasonal influences on baseline concentrations of GABA and glutamate across five different subcortical brain regions of healthy subjects. Moreover, associations of light and radiation with derived neurotransmitter measures were tested. Hence, we found stable patterns of neurotransmitter levels throughout the year. Abstract Seasonal

Glia, Volume 70, Issue 8, Page 1536-1553, August 2022., 2022 Main Points Astrocyte signaling controls synaptic strength in a hippocampal memory circuit. The control is circuit‐specific and gated by the cytokine TNFα. Inflammation/infection over‐activates this mechanism causing synaptic alteration and reduced memory performance.

Highlights of neuroanatomical discoveries of the mammalian gonadotropin‐releasing hormone system
Journal of Neuroendocrinology, Volume 34, Issue 5, May 2022., 2022 Abstract The anatomy and morphology of gonadotropin‐releasing hormone (GnRH) neurons makes them both a joy and a challenge to investigate. They are a highly unique population of neurons given their developmental migration into the brain from the olfactory placode, their relatively small number, their largely scattered distribution within the rostral ...

Emerging Role of Neuron‐Glia in Neurological Disorders: At a Glance
Oxidative Medicine and Cellular Longevity, Volume 2022, Issue 1, 2022., 2022 Based on the diverse physiological influence, the impact of glial cells has become much more evident on neurological illnesses, resulting in the origins of many diseases appearing to be more convoluted than previously happened. Since neurological disorders are often random and unknown, hence the construction of animal models is difficult to build ...

Protein kinase D promotes activity‐dependent AMPA receptor endocytosis in hippocampal neurons
Traffic, Volume 22, Issue 12, Page 454-470, December 2021., 2021 Synaptic connections in the brain are continuously weakened or strengthened in response to changes in neuronal activity. This process, known as synaptic plasticity, is the cellular basis for learning and memory. An important aspect is the trafficking of AMPA receptors (AMPARs), the main mediators of fast excitatory transmission in the brain.

A Marr's Three‐Level Analytical Framework for Neuromorphic Electronic Systems
Advanced Intelligent Systems, Volume 3, Issue 11, November 2021., 2021 Under David Marr's famous three‐level analytical framework originally proposed for studying the brain, the problem of how to build neuromorphic electronic systems is defined in a tractable way. Selectively surveyed advances in this field are given significance as appropriate from the computational level, algorithmic level or implementation level.

Journal of Neuroscience Research, Volume 99, Issue 11, Page 2774-2792, November 2021., 2021 Abstract Myelination is crucial for the development and maintenance of axonal integrity, especially fast axonal action potential conduction. There is increasing evidence that glutamate signaling and release through neuronal activity modulates the myelination process.
