focus

  1. a term used to describe a firm's concentration on a single or limited range of business activities. By focusing on a ‘core activity’ the firm is better able to reap the benefits of SPECIALIZATION and access ECONOMIES OF SCALE, increase its MARKET SHARE and concentrate management's attention and capabilities on ‘what they know best’. On the debit side, however, over-specialization may make the firm vulnerable to cyclical and secular downturns in demand while limiting opportunities for achieving long-run growth. See HORIZONTAL INTEGRATION, COMPETITIVE STRATEGY. Contrast DIVERSIFICATION.
  2. a means of organizing production. See PRODUCT-FOCUSED LAYOUT.
  3. a means of conducting market research by the use of ‘focus groups’. See MARKETING INTELLIGENCE.
  4. competing in (‘targeting’) one MARKET SEGMENT only (also known as niche targeting or marketing.) See CONCENTRATED MARKETING or TARGETING STRATEGY, DIFFERENTIATED MARKETING or TARGETING STRATEGY.

However, studies in the literature have not proven whether this condition represents the visible part of a more distant disorder of brain development or an epileptogenic focus (2, 5, 8-12).
The localisation of epileptogenic focus can be made by clinical symptoms, electroencephalography, computed tomography, magnetic resonance imaging, functional magnetic resonance imaging, SPECT and PET studies.

The third stage is the epileptogenic focus where the patient is operated on by a team of specialist surgeons, he said.
Because the mechanism of VNS therapy is different from pharmacotherapy and traditional surgery, and it can be used to reduce seizure burden by stimulating the vagus nerve instead of localizing the epileptogenic focus. Moreover, it has been found that VNS improves attention, cognition, behavior, mood, and quality of life (QOL) besides of reducing seizure burden.[sup][3],[4],[5],[6],[7] Therefore, VNS therapy provides an alternative method for patients with PRE, especially for those with multifocal or unlocalized epileptogenic foci.
(17) For example, it has been found that in temporal lobe epilepsy (TLE) with left lateralization of epileptogenic focus (LEFl), there are more pronounced alterations in terms of verbal memory and language, while in TLE with right lateralization of epileptogenic focus (LEFr), more pronounced disorders in visuo-perceptive functions and visuo-spatial memory can be expected.
With a new-onset seizure, the imaging priority should be focused on ruling out an acute process, rather than visualizing a subtle epileptogenic focus. For example, venous infarction related to dural venous sinus thrombosis may be the suspected underlying cause of a new-onset seizure in the pediatric population; thus, an MR or CT venogram should be performed.
A quantitative analysis of spiking in patients with temporal lobe epilepsy by Lieb et al [1] has revealed that the epileptogenic focus (the region of the brain that triggers a seizure) generates spikes at maximum mean spiking rate and minimum coefficient of variation, and minimum variance in inter-spike intervals.
