= Neurethic =

Neurethic is a research project in cognitive neuroscience based on an experimental and ethical approach, employing a methodology that includes behavioral, cognitive, and neurophysiological measures. It unfolds along three main axes:

* Neurethic Health addresses the cognitive and emotional issues of patients suffering from neurodegenerative diseases (in particular multiple sclerosis) and neurodevelopmental pathologies.
* Neurethic Interaction studies the neurophysiology of human-machine interaction and the perception of the human element in hybrid interactions.
* Neurethic XR examines the benefits and limitations of extended reality on cognition, especially in learning situations.

The experiments take place in a hospital setting and within the Neurethic Lab, an experimental space equipped with a wide variety of neuro and electrophysiological measurement tools, such as electroencephalography, electrodermal activity, cardiac activity, and eye tracking. The Neurethic Lab also enables the creation of stimuli and immersive environments through extended reality devices.

Individual pretrial Baseline (IPB)

10.227.0.12 :

== Definition ==

The value where we need to put back the participant before the start of trial. It is important to fix an instruction of a minimum force to apply because without it participant may hold the sensor too loosely (Nazir & al., 2017).

The term of baseline to name this value can be discussed to have the more appropriate and consensual name. This can also be called a threshold.

This value was set to 1.5N in previous articles with additional informations that this value tend to decrease (18.62%) over time without instructions (Nazir & al., 2017) and there isn't a gender effect (Blampain & al., 2018).

== New approaches ==

''(The previous value used for baseline was based on ...)'' Research on grip force sensor don't modified this baseline for each participant. Due to the lack of subjectivity of this value, some questions emerged on the possible need to adjust it for each participant and the way to do it.

This method is based on a weighted mean with 2 values: comfortable holding and cell droping. The mean of the grip force signal is computed during a 60 seconds record when the only instruction given to the participant is to "hold the cell in a confortable way" following the example of the experimenter on the way to hold the cell according to the Lille setup (see image below (recup photo Olivier)). Next, we ask him to release gradually the pressure on the cell until it drops on a box full of foam (to prevent any damage on the cell). This step is repeated [3] times and we take the mean of the 3 minimum values before the cell drops.

We can compute a baseline / threshold value with 80% of the confort mean and 20% of the drop mean following this calculation:

baseline / threshold = 0.8 x confort + 0.2 x drop

This method is based on a mix of 2 values: comfortable holding and cell droping in a weighted mean. The mean of the grip force signal is computed on a 60 seconds record when the only instruction given to the participant is to "hold the cell in a confortable way" following the example of the experimenter on the way to hold the cell according to the Lille setup (see image below)
