# Cerebellar tDCS and visuomotor adaptation

Code to analyse behavioural data of visuomotor adaptation task performed during anodal or sham cerebellar stimulation.

#### written by Caroline Nettekoven, University of Oxford, 2016 - 2022.

- Within-subject, sham-controlled anodal tDCS study.

- Real stimulation parameters: 1.5 mA, 20 min

## Description

### FILES

All are stored in folder `./data`

Files available: \

main_data.txt             contains behavioural data \

main_subjectlist.txt      contains subject list

### DATA

(text file ending in _data) \

contains error data and information about experimental protocol

column 1    =     error \

column 2    =     block number \

column 3    =     trial number (within-block) \

column 4    =     target \

column 5    =     rotation \

column 6    =     visual feedback ON yes or no \

column 7    =     Reaction Time \

column 8    =     Movement Onset \

column 9    =     Movement Offset \

column 10   =     Timepoint of peak velocity (is the same as RT) \

column 11   =     Peak Velocity \

column 12   =     Artefactual trial yes or no

### SUBJECTS

(text file ending in _subjectlist) \

contains subject name (is stored seperately from _data because matlab can't write out strings and numbers to the same text file)

## Steps to perform analysis.

1. Load datasets and calculate performance indices\

   Run `tdcs_get_behav_data.R`

     

2. Calculate statistics\

   Run `tdcs_stats.R`
