Cover Illustration: Confocal microscopy image of primary culture of female astrocytes, stimulated with bacterial lipopolysaccharide (LPS) and treated with insulin-like growth factor (IGF-1). The image shows the reactive morphology of the cytoskeleton (glial fibrillary acidic protein-green), induced by LPS. IGF-1 cannot reduce reactivity in female astrocytes, only in male astrocytes, indicating that male and female astrocytes show different inflammatory outcomes with LPS administration and IGF-1 treatment.

Nicotine, the main psychoactive component in tobacco smoke, plays a major role in tobacco addiction, producing a high morbidity and mortality in the world. A great amount of research has been developed to elucidate the neural pathways and neurotransmitter systems involved in such a complex addictive behavior. The endocannabinoid system, which has been reported to participate in the addictive properties of most prototypical drugs of abuse, is also implicated in nicotine dependence. This review summarizes and updates the main behavioral and biochemical data involving the endocannabinoid system in the rewarding properties of nicotine as well as in nicotine withdrawal and relapse to nicotine-seeking behavior. Promising results from preclinical studies suggest that manipulation of the endocannabinoid system could be a potential therapeutic strategy for treating nicotine addiction

SoxD genes are required for adult neural stem cell activation. Cell Reports, 2022 Feb 1;38(5):110313. doi: 10.1016/j.celrep.2022.110313.
On the Cover: The adult neurogenic niche in the hippocampus is maintained through activation of reversibly quiescent neural stem cells (NSCs). The cover highlights NSCs in the hippocampal dentate gyrus with radial processes GFAP+ (green) expressing transcription factor Sox6 (red). Most of the NSCs are quiescent except for those expressing MCM2 (activated, white). Li et al. report that Sox6 and Sox5 are required for NSC activation and for the generation of new neurons in the adult hippocampus in mice. Image credit: Cristina Medina-Menéndez

In this article by Carlos A. Saura, Jaume Esteve, and co-workers, show fabrication of suspended silicon microphotodiodes as a simple and cost-effective wire-less microtool for delivering photocurrent in liquid media. Electrical and electrochemical characterization of microphotodiodes under on/off illumination conditions was performed. Their effectiveness as remote photovoltaic cells for life science applications was evaluated in vitro in mouse cultured neurons. The picture shows silicon microphotodiodes bound to the cell surface of a neuron captured by scanning electron microscopy.

Formin 2 links neuropsychiatric phenotypes at young age to an increased risk for dementia. EMBO J. 2017 Oct 2;36(19):2815-2828.
Deregulation of the actin cytoskeleton regulator Formin 2 is a common denominator of post-traumatic stress disorders and age-dependent Alzheimer’s disease phenotypes, possibly explaining their clinical connection. Agis-Balboa et al. provide molecular insight to the phenomena that people suffering from PTSD at young age have an increased risk to develop Alzheimer’s disease. The data suggest that the Formin 2 protein and aberrant gene-expression play a key role.
Gonzalez-Fernandez C, Arevalo-Martin A, Paniagua-Torija B, Ferrer I, Rodriguez FJ,Garcia-Ovejero D. Wnts Are Expressed in the Ependymal Region of the Adult Spinal Cord. Mol Neurobiol2016 Oct 8. doi: 10.1007/s12035-016-0132-8.
In rodent spinal cord, neural precursors/stem cells are arranged around the central canal, like the seeds around the central placenta (white core) of the kiwi fruit. But in adult humans central canal is collapsed, and ependymal cells rearrange forming cell aggregations like those formed by seeds in the pomegranate. In the current paper, we show that Wnts are expressed both in rats and human ependymal region, but with a different pattern, suggesting a role for this family of proteins in both species, but probably different functional implications in each of them.

The study explores the synaptic mechanisms of firing selectivity by CA1 pyramidal cells during sharp-wave ripples. Using unsupervised clustering of ripple waveforms, the authors show how an intracellular synaptic depolarization determines firing preference during some sharp-wave ripple events. This mechanism is impaired in epileptic rats and cells fire indiscriminately following global synaptic influences. The image depicts the waves beating the seashore and two spiky shadows at the edge choosing a ripple to jump. Image from Adam Goldberg, used under license from Shutterstock.com.

Leal-Campanario, R., Delgado-García, J.M., Gruart, A. Electrical stimulation of the rostral medial prefrontal cortex inhibits reflex blinks and the expression of conditioned eyelid responses, but does not affect its acquisition, in behaving rabbits. Journal of Neuroscience 2013; 33 (10): 4378-86. ISSN: 0270-6474.
The rostromedial prefrontal cortex in rabbits is a potent inhibitor of acquired eyelid responses until the need for the acquired response is fully confirmed. In this regard, the rostromedial prefrontal cortex seems to act as flip-flop mechanism controlling the expression of reflex and acquired behaviors depending on the animal environmental circumstances.

Activity-dependent plasticity is important for synaptic refinement during cortical development. The cover shows that a specific spike pattern in individual presynaptic layer 4 neurons (blue traces) can induce long-term depression (LTD) without the involvement of the postsynaptic neuron. This presynaptic spike pattern-dependent LTD (p-LTD) requires release of glutamate (green spheres) activating presynaptic NMDA receptors (red rods).

Production of new neurons in the adult brain goes down with age and this decline may underlie age-related cognitive impairment. Encinas et al. (pages 566–579) show that aging is associated with the decrease in the number of neural stem cell in the hippocampus. These cells disappear, after a rapid series of divisions, via their conversion into astrocytes. The image depicts stem cells (teal) and neuronal nuclei (yellow), with the autumn trees with falling leaves symbolizing the loss of cells during aging. Image created by Elena Nikanorova, Ann-Shyn Chiang, and Grigori Enikolopov.
