On the transience or stability of subthreshold psychopathology [PDF]
Scientific Reports, 2021 AbstractSymptoms of psychopathology lie on a continuum ranging from mental health to psychiatric disorders. Although much research has focused on progression along this continuum, for most individuals, subthreshold symptoms do not escalate into full-blown disorders.

BIOPHYSICAL PROPERTIES OF SUBTHRESHOLD RESONANCE OSCILLATIONS AND SUBTHRESHOLD MEMBRANE OSCILLATIONS IN NEURONS [PDF]
Journal of Biological Systems, 2016 Subthreshold-level activities in neurons play a crucial role in neuronal oscillations. These small-amplitude oscillations have been suggested to be involved in synaptic plasticity and in determining the frequency of network oscillations. Subthreshold membrane oscillations (STOs) and subthreshold resonance oscillations (SROs) are the main constituents ...

An Ultra-Low Energy Subthreshold SRAM Bitcell for Energy Constrained Biomedical Applications
Journal of Low Power Electronics and Applications, 2014 Energy consumption is a key issue in portable biomedical devices that require uninterrupted biomedical data processing. As the battery life is critical for the user, these devices impose stringent energy constraints on SRAMs and other system on chip (SoC)

International Psychiatry, 2011 Are we in need of including in our diagnostic systems a new category of subthreshold psychiatry? Studies have shown that we are faced in our daily clinical practice with many patients who do not fulfil the criteria of either ICD-10 or DSM-IV (at best they may be included under 'atypical', 'unspecified' or 'not elsewhere classified'). Subthreshold cases

Subthreshold depression in Parkinson's disease [PDF]
International Journal of Geriatric Psychiatry, 2009 AbstractObjectiveIt is estimated that 40% of patients with Parkinson's disease (PD) are clinically depressed, however, little is known about the frequency and associated features of subthreshold depression in PD. The current study sought to determine the prevalence of subthreshold depression (sD) and to further characterize the associated features in a

Selective Attention in Multi-Chip Address-Event Systems
Sensors, 2009 Selective attention is the strategy used by biological systems to cope with the inherent limits in their available computational resources, in order to efficiently process sensory information. The same strategy can be used in artificial systems that have
