V9. Distinct contributions of dorsal and ventral streams to imitation of transitive and intransitive gestures: Evidence from acute stroke patients
Meaningful gestures are one of the key features of social interaction and comprise both object-associated transitive movements (e.g. hammering) as well as intransitive movements referring to a communicative content (e.g. waving goodbye). The ability to imitate meaningful gestures is frequently impaired in apraxia due to left-hemispheric stroke. However, the pathophysiology behind these deficits so far remained unresolved. A dual stream-model for a dichotomized organisation of higher cognitive functions such as language or praxis has been proposed, with a dorsal stream involved in sensorimotor processing and a ventral strea...

Defining abnormal slow EEG activity in acute ischaemic stroke: delta/alpha ratio as an optimal QEEG index
Ischaemic stroke (IS) produces abnormal, slow EEG activity - particularly in the delta frequency range (1-4 Hz) - and attenuation of normative, faster activity, particularly in the alpha frequency range (8-12 Hz; e.g., Jordan, 2004; Hirsch et al., 2013). A recent review (Finnigan and van Putten, 2013) emphasises that particular QEEG indices, which are sensitive to such cerebral pathophysiology following IS, can inform clinical decision-making including: (1) continuous monitoring to inform about the efficacy of acute reperfusion therapies, and; (2) outcome prognostication and clinical management decisions based on brief, pre-discharge EEG.

ID 127 – Small world characteristics of cortical connectivity in acute stroke
After cerebral ischemia, disruption and subsequent reorganization of functional connections occur both locally and remote to the lesion. Recently, brain complexity has been described using the graph theory, an elegant approach which depicts important properties of complex systems by quantifying topologies of network representations. We tested whether ischemic stroke may determine changes in smallworldness of cortical networks as measured by cortical sources of EEG.

ID 126 – Cortical connectivity and lesion volumes correlation in acute stroke patients: A study via graph theory from EEG data
Functional connectivity is essential for brain functions. Focal brain lesions could have important remote effects on the functions of distant brain regions even if outside the damaged area. Network dysfunction may contribute to neurological deficits observed for example after stroke. We explored how functional network characteristics, measured via EEG recordings, correlate with the lesion volume on MRI.

ID 452 – Sympathetic skin response in stroke patients
Sympathetic dysfunction could lead to life-threatening complications. The aim of this study was to investigate the relationship between the size, location, nature of the lesion, and the sympathetic skin response (SSR).Thirty patients with stroke and 30 healthy subjects were included in this study. All patients were investigated by using brain imaging and clinical scales. SSRs were elicited on four extremities in both groups. Latency and amplitude values of the responses were measured. In the patient group, SSR were analyzed both in the early (in the first month) and the late stages (one month later first recording) of the patients.

Resolution of cerebral pathophysiology immediately following thrombectomy in acute ischaemic stroke: Monitoring via quantitative EEG
Quantitative EEG (QEEG) has demonstrated value in assessment of cerebral pathophysiology following acute ischaemic stroke (AIS; e.g., (Finnigan et al., 2013). Various reports indicate that EEG/QEEG can promptly detect cerebral responses to successful reperfusion therapy, even when this cannot be assessed clinically (Finnigan et al., 2006; de Vos et al., 2008, Finnigan et al., 2013). Additionally QEEG can indicate lack of favourable response to therapy, (e.g. unsuccessful alteplase) and may help expedite decisions regarding intra-arterial interventions (e.g.
