The Poole-Frenkel laws and a pathway to multi-valued memory [PDF]
, 2019 We revisit the mechanism of Poole-Frenkel non-ohmic conduction in materials of non-volatile memory. Percolation theory is shown to explain both the Poole and Frenkel dependencies corresponding to the cases of respectively small and large samples compared to the correlation radii of their percolation clusters.

Redundant neural vision systems: competing for collision recognition roles [PDF]
, 2013 Ability to detect collisions is vital for future robots that interact with humans in complex visual environments. Lobula giant movement detectors (LGMD) and directional selective neurons (DSNs) are two types of identified neurons found in the visual ...

A potential tumor suppressor role of PLK2 in glioblastoma
FEBS Open Bio, EarlyView.PLK2 was consistently downregulated in GBM tissues. Overexpression of PLK2 in GBM cell lines U87MG and U251 reduced their tumorigenic potential and enhanced cell cycle arrest and apoptosis. Suggesting that PLK2 overexpression could potentially be leveraged as a therapeutic strategy to inhibit tumor progression and enhance apoptosis, providing new ...

Vision at A Glance: Interplay between Fine and Coarse Information Processing Pathways [PDF]
arXiv, 2020 Object recognition is often viewed as a feedforward, bottom-up process in machine learning, but in real neural systems, object recognition is a complicated process which involves the interplay between two signal pathways. One is the parvocellular pathway (P-pathway), which is slow and extracts fine features of objects; the other is the magnocellular ...

Oriented tensor reconstruction: tracing neural pathways from diffusion tensor MRI [PDF]
, 2002 In this paper we develop a new technique for tracing anatomical fibers from 3D tensor fields. The technique extracts salient tensor features using a local regularization technique that allows the algorithm to cross noisy regions and bridge gaps in the ...

Combined EEG-fMRI and tractography to visualise propagation of epileptic activity [PDF]
, 2007 In a patient with refractory temporal lobe epilepsy, EEG-fMRI showed activation in association with left anterior temporal interictal discharges, in the left temporal, parietal and occipital lobes. Dynamic causal modelling suggested propagation of neural

Neural pathways underlying vocal control
Neuroscience & Biobehavioral Reviews, 2002 Vocalization is a complex behaviour pattern, consisting of essentially three components: laryngeal activity, respiratory movements and supralaryngeal (articulatory) activity. The motoneurones controlling this behaviour are located in various nuclei in the pons (trigeminal motor nucleus), medulla (facial nucleus, nucl. ambiguus, hypoglossal nucleus) and

Art meets science – empowering stroke patients to regain muscular control through creative graphics technology, psycho-physiology and neuroplasticity. [PDF]
, 2012 Treating patients with a cerebrovascular accident or stroke is complicated by severity and site of brain lesion. Muscular control is lost when neural pathways are interrupted or damaged due to embolus, thrombosis or ruptured aneurysm.

Self-generated neural activity : models and perspective [PDF]
, 2009 Poster presentation: The brain is autonomously active and this self-sustained neural activity is in general modulated, but not driven, by the sensory input data stream [1,2].
