CCNS occasionally receives applications for internships from students wishing to spend part of a summer vacation or a period after graduation in one of our laboratories.  We do not advertise such positions, but look at each enquiry carefully.  Usually, they are a short email statement of what the applicant is seeking, and why, and a short CV.  That is all we require.  The office then passes this on to the PI of an appropriate lab who may choose to pursue things.
