function pushbutton1_Callback(hObject, eventdata, handles) %Cargar archivo *.csv
[nombre direccion]=uigetfile('*.csv','Escoger Archivo *.CSV');
if nombre==0
return
end
EEGDATOS1=importdata(fullfile(direccion,nombre));
EEGDATOS1=EEGDATOS1.data;
function popupmenu_Callback(hObject, eventdata, handles)
EEGDA=EEGDATOS1 % in this line gives me the error HELP
T7=EEGDA(:,2:2);
%%Frecuencia de Muestreo y tiempo
Fs=128;
T=1/Fs;
tiempo=size(T7)/Fs;
tt=0:1/Fs:tiempo;
H=get(handles.EscogerElectrodo,'Value')
switch H
case 2 % AF3
set(handles.mensaje,'String','AF3')
drawnow();
case 3 % F7
set(handles.mensaje,'String','F7')
drawnow();

You need
handles.EEGDATOS1 = EEGDATOS1
guidata( hObject, handles )
at the end of your pushbutton callback and
EEGDA = handles.EEGDATOS1
at the start of your popup menu callback.
Each function in a GUI, just like functions anywhere else that are not nested, has its own scope and workspace. Once the function ends so does its workspace. The call to the guidata function updates the UI's 'handles' structure onto which has now been added your data.
