Here, we extract a continuous, time-resolved marker of alertness from fMRI data alone.  ...  We demonstrate that this fMRI alertness marker, calculated in a short pre-stimulus interval, captures trial-to-trial behavioral responses to incoming sensory stimuli.  ...  This finding extends a body of prior work linking fMRI spontaneous activity with behavior and perception (e.g., Sadaghiani et al., 2009; Kelly et al., 2008; Thompson et al., 2013; Sadaghiani et al., 2015  ...

Near infrared spectroscopy – a bioengineering approach to traumatic brain injury

Vassilios Kontojannis, Martyn Boutelle
We have recruited 205 patients; intracranial haematomas of volume>3.5ml, and deep<2.5cm from the surface of the brain, the sensitivity was found to be 89% and the negative predictive value 93.9%.  ...  With a cross study negative predictive value of 90% and a positive predictive value of 77%, NIRS did not meet the requirements set by this review either as a diagnostic or triage tool.  ...  Lynch et al. found a deviation less than 10% between the invasive (jugular bulb) and non-invasive (cerebral NIRS) determination of the oxygen saturation. Colquhoun et al.  ...

Detection of higher visual function deficits and validation of multifocal pupillography in stroke, chiasmal compression and anterior ischemic optic neuropathy [article]

Brendan Tonson-Older, University, The Australian National
The relatively new invention of multifocal pupillographic objective perimetry (mfPOP) provides a number of benefits from other forms of perimetry.  ...  This thesis examines these visual deficits in the common neurological diseases of stroke, chiasmal compression, and anterior ischemic optic neuropathy (AION).  ...  Multifocal pupillographic objective perimetry (mfPOP) is a relatively new technology originating from work on visual evoked potentials; it attempts to provide the benefits of automated perimetry while  ...

Modulatory effects of emotional arousal on cueing during sleep and retrieval mechanisms

Mick Lehmann
Alpha power decreases during successful recognition have been repeatedly observed in both, scalp (see for a review) and intracranial hippocampal EEG studies Staresina et al., 2016) .  ...  et al., 2012; Schönauer et al., 2014) , a more recent study found that the memory performance of a no-cueing sleep group did not differ from the recall of uncued words in a cueing sleep .  ...  Cueing resulted in a robust preferential strengthening of negative arousing as compared to neutral memories.  ...
