If you insist, you might want to consider this (but don't quote me
quoting this quote from J.A. Gray and J.N.P. Rawlins:
[quote] It is now well established that the theta rhythm is generated
in at two locations in the hippocampal foormation (in CA1 and
the dentate gyrus[..]) and at another location in the entorhi-
, nal cortex[..], and that these generators are under the con-
trol of pacemaker cells in the medial septal area. The func-
tional significance of theta remains an enigma, however.
Vinogradova (1975) and O'Keefe have suggested that the func-
tion of theta is to quantize time with respect to the
passage of different items of information through the SHS
(=septohippocampal system, PU).
An alternative hypothesis is that theta paces the passage
of successive items of information around all the loops
that make up the SHS and the Papez-circuit.
..there are two types of theta. The first (atropine- resis-
tant) type is associated with movement.[..].The second (atro-
pine sensitive) is not associated with movement, and may be
blocked by systemic anticholinergics, and is of relatively
Mind you, the theta rhythm is an electrocortically measurable rhythm
of around 7.7 Hz. Gray and Rawlins do not, however, explicitly asso-
ciate the theta rhythm with time perception. It is up to you to
abuse this kind of information :-)
