Amblyopia is a developmental disorder of the visual cortex that is often accompanied by strong suppression of one eye. We present a new technique for measuring and treating interocular suppression in patients with amblyopia that can be deployed using virtual reality goggles or a portable iPod Touch device.

Here, we present a protocol to detect the presence of neutrophils in fixed/permeabilized histology sections and assess the activation state of live purified neutrophils. In particular, the MUB40 peptide binds lactoferrin present in neutrophil-specific and tertiary granules. Exposure of the granule contents through either permeabilization or neutrophil activation allows for the marking of neutrophils.

Human In Vitro Suppression as Screening Tool for the Recognition of an Early State of Immune Imbalance

Tregs are potent suppressors of the immune system. There is a lack of unique surface markers to define them, hence, definitions of Tregs are primarily functional. Here we describe an optimized in vitro assay capable of identifying immune imbalance in subjects at risk to develop T1D.
FAQs
The key change is reduced synchrony among neuronal populations contributing to the rhythm. Movement, imagined movement, or tactile input engages the sensorimotor system, and this coordinated engagement disrupts the previously organized oscillatory pattern. The resulting event-related desynchronization gives researchers a measurable signal of motor-system participation rather than merely a record of whether physical movement occurred.
Mu frequency suppression can accompany actual movement even when no movement occurs. Motor imagery provides an internally generated condition for engaging motor circuits, while tactile stimulation supplies sensory input that also affects the sensorimotor rhythm. Comparing these conditions helps investigators examine motor-system engagement across action, imagined action, and touch within a common neural measure.
Electroencephalography and magnetoencephalography can detect reductions in rhythmic activity over the sensorimotor cortex. These recordings allow studies to relate the signal to movement, motor imagery, or tactile stimulation, making the phenomenon useful when the research question concerns cortical activity rather than behavioral output alone. The measured change is interpreted as event-related desynchronization.
A practical measurement workflow links a recorded brain signal to a defined motor-related condition. Investigators acquire EEG or MEG while participants perform a movement, imagine one, or receive tactile stimulation, then examine whether the mu rhythm shows suppression during that condition. The outcome is an event-related desynchronization that can index sensorimotor engagement.
In brain-computer interfaces, the relevant signal is treated as a control feature rather than only a physiological observation. Movement-related mu suppression can be measured and translated into control commands, creating a pathway from sensorimotor brain activity to device operation. Its value depends on detecting neural engagement associated with movement or motor imagery.
Clinically oriented studies use this measure to assess motor cortical function and to monitor changes relevant to neurological injury. In neurorehabilitation research, sensorimotor feedback is investigated as a way to track or potentially promote recovery. Thus, the same neural marker can support functional assessment and research on interventions after injury, without requiring the signal to represent overt movement alone.
