NEUROIMAGING

Magnetic resonance

Magnetic resonance imaging is a non-invasive imaging method that uses the magnetic properties of the atoms of the human body. It allows for the study the internal structures of the body in terms of both their structure and function. CBM owns a 3T Magnetom Prisma scanner (Siemens).

Spectroscopy

Functional near infrared spectroscopy is a non-invasive method of functional neuroimaging of the brain. It uses the light-absorbing properties of haemoglobin and deoxygenated haemoglobin, allows for the visualisation of the activity of the cerebral cortex and study of higher cognitive processes.

Electrophysiology

Electroencephalography (EEG) is a non-invasive method of measuring the bioelectrical activity of the brain. The measurement is carried out using electrodes detecting changes in electrical potentials on the surface of the head. The main advantage of EEG is a good time resolution and low cost of the test.

BRAIN STIMULATION

Electric stimulation

Transcranial stimulation with the use of electric current is a non-invasive method that uses electric current of low amperage. During the test, the current is sent to the brain via electrodes placed on the scalp. The electric field generated in this way modulates neuronal activity.

Magnetic stimulation

Transcranial magnetic stimulation is based on electromagnetic induction, leading to a change in the neuronal activity of the stimulated area. The method allows for non-invasive interference with the functioning of specific areas of the brain, temporarily increasing or decreasing their activity, and thus allows for the study the impact of these changes on the course of cognitive processes.

SENSORY STIMULATION

Touch and pain

Our studies exploit thermal, electrical and pressure stimuli. Research concerns both simple sensory perception and the interaction of higher cognitive processes with these experiences (e.g., the placebo effect). The application of stimuli is safe and does not damage the skin. We own modern and certified devices for this type of research,

Sight and hearing

We conduct behavioural research using computer stimulus presentation. In addition to traditional computer tasks, we use in our experiments tools such as Oculus Rift virtual reality goggles or the EyeLink 1000 eye tracker, which allows for the tracking of the visual attention, eye movements and the size of the pupils of the tested person.
