The work referred to is:
Nerve cell damage in mammalian brain after exposure to microwaves from
GSM mobile phones.

The possible risks of radio-frequency electromagnetic fields for the
human body is a growing concern for our society. We have previously
shown that weak pulsed microwaves give rise to a significant leakage
of albumin through the blood-brain barrier. In this study we
investigated whether a pathologic leakage across the blood-brain
barrier might be combined with damage to the neurons. Three groups
each of eight rats were exposed for 2 hr to Global System for Mobile
Communications (GSM) mobile phone electromagnetic fields of different
strengths. We found highly significant (p< 0.002) evidence for
neuronal damage in the cortex, hippocampus, and basal ganglia in the
brains of exposed rats.
This seems to disagree with previous work:
Effect of global system for mobile communication (GSM) microwave
exposure on blood-brain barrier permeability in rat.

We investigated the effects of global system for mobile communication
(GSM) microwave exposure on the permeability of the blood-brain
barrier using a calibrated microwave exposure system in the 900 MHz
band. Rats were restrained in a carousel of circularly arranged
plastic tubes and sham-exposed or microwave irradiated for a duration
of 4 h at specific brain absorption rates (SAR) ranging from 0.3 to
7.5 W/kg. The extravasation of proteins was assessed either at the end
of exposure or 7 days later in three to five coronal brain slices by
immunohistochemical staining of serum albumin. As a positive control
two rats were subjected to cold injury. In the brains of freely moving
control rats (n = 20) only one spot of extravasated serum albumin
could be detected in one animal. In the sham-exposed control group (n
= 20) three animals exhibited a total of 4 extravasations. In animals
irradiated for 4 h at SAR of 0.3, 1.5 and 7.5 W/kg (n = 20 in each
group) five out of the ten animals of each group killed at the end of
the exposure showed 7, 6 and 14 extravasations, respectively. In the
ten animals of each group killed 7 days after exposure, the total
number of extravasations was 2, 0 and 1, respectively. The increase in
serum albumin extravasations after microwave exposure reached
significance only in the group exposed to the highest SAR of 7.5 W/kg
but not at the lower intensities. Histological injury was not observed
in any of the examined brains. Compared to other pathological
conditions with increased blood-brain barrier permeability such as
cold injury, the here observed serum albumin extravasations are very
modest and, moreover, reversible. Microwave exposure in the frequency
and intensity range of mobile telephony is unlikely to produce
pathologically significant changes of the blood-brain barrier
permeability.
