Inorg Chem . 2001 May; 40(10):2270-4. PMID: 11327901
There is no experimental proof documented in the literature for the existence of any beryllium peroxide compound. All recent pertinent preparative attempts described in this work, using a range of...

Nicol S, Andersen N, Phillips N, Berger R
Neurosci Lett . 2000 Mar; 283(1):49-52. PMID: 10729631
The failure to identify rapid eye movement sleep (REMS) in an early study of the echidna at an unmeasured ambient temperature (T(a)) was unexpected, as its brain stem structures resemble...
3.
Mintz E, Phillips N, Berger R
Neurosci Lett . 1999 Jan; 258(2):61-4. PMID: 9875527
Daily infusions of melatonin restore sleep suppressed by continuous bright light in pigeons. To test whether melatonin could also induce sleep in pigeons on a 12:12 h light-dark cycle (LD),...

Kumar R, Berger R, DUNSKER S, Keller J
Spine (Phila Pa 1976) . 1996 Jan; 21(1):18-26. PMID: 9122758
Study Design: Cranial and spinal dura from nine Sprague Dawley male rats were examined immunocytochemically for the presence of nerve fibers and mast cells and for innervation. The posterior longitudinal...

Berger R, Phillips N
Behav Brain Res . 1995 Jul; 69(1-2):65-73. PMID: 7546319
Phylogenetic and ontogenetic associations between sleep and endothermy are consistent with the hypothesis that sleep evolved in conjunction with endothermy to offset the high energetic cost of endothermy. The electrophysiological...

Berger R, Phillips N
Am J Physiol . 1994 Oct; 267(4 Pt 2):R945-52. PMID: 7943436
Sleep patterns and circadian rhythms of body temperature, activity, body weight, and electroencephalographic (EEG) power spectra of pigeons were compared among three photic conditions: a 12:12-h light-dark cycle (LD), followed...

Castellini M, Milsom W, Berger R, Costa D, Jones D, Castellini J, et al.
Am J Physiol . 1994 Mar; 266(3 Pt 2):R863-9. PMID: 8160882
Although breath holding during diving has been studied extensively in seals, the recent observation that these mammals also exhibit long-duration apnea while apparently sleeping has not been systematically examined. This...

Berger R, Zuccarello M, Keller J
Neuroreport . 1994 Jan; 5(4):519-21. PMID: 7516199
The dura mater has been implicated as a tissue where vascular headache develops. Identification of the neural components of this tissue is a prerequisite for understanding the mechanisms of this...

Arand A, Zuccarello M, Skidmore B, Berger R, Keller J
Acta Neurochir (Wien) . 1994 Jan; 127(1-2):103-11. PMID: 7524275
While the presence of a robust perivascular neural network accompanying cerebral and dural blood vessels that contain various neuropeptides is well documented, the functional significance of this innervation is unclear....
