I went on ssris exactly one year ago today. It was a really difficult decision at the time. I’m trying so hard to be happy and healthy and honest, y'all and some days I feel worse and some days I fuck it up but for the first time, I am trying. Big hugs to anybody struggling with their brain or their life, I love you.
that relay information from the ear to the brain can change in
significant ways in response to the noise level in the environment. That’s one major finding of a study in PNAS.
Expose the cells to loud sounds for a prolonged period of time, and
they alter their behavior and even their structure in a manner that may
aid hearing in the midst of noise. End the ruckus, and the cells change
again to accommodate for quieter environs.
The brains of people with type 1 diabetes show signs of accelerated aging that correlate with slower information processing, according to research led by the University of Pittsburgh Graduate School of Public Health.

Research: “White matter hyperintensities in middle-aged adults with childhood-onset type 1 diabetes” by Karen A. Nunley, PhD, Christopher M. Ryan, PhD, Trevor J. Orchard, MBBCh, MMedSci, Howard J.

Image: The MRIs showed that 33 percent of the people with type 1 diabetes had moderate to severe levels of white matter hyperintensities (markers of damage to the brain’s white matter, present in normal aging and neurological disorders) compared with 7 percent of their non-diabetic counterparts.

3D Reconstruction of Neuronal Networks Provides Unprecedented Insight into Organisational Principles of Sensory Cortex
Researchers at the Max Planck Institute for Biological Cybernetics (Germany), VU University Amsterdam (Netherlands) and Max Planck Florida Institute for Neuroscience (USA) succeed in reconstructing the neuronal networks that interconnect the elementary units of sensory cortex – cortical columns.
The researchers found that in contrast to the decade-long focus of describing neuronal pathways within a cortical column, the majority of the cortical circuitry interconnects neurons across cortical columns. Moreover, these ‘trans-columnar’ networks are not uniformly structured. Instead, ‘trans-columnar’ pathways follow multiple highly specialized principles, which for example mirror the layout of the sensory receptors at the periphery. Consequently, the concept of cortical columns, as the primary entity of cortical processing, can now be extended to the next level of organization, where groups of multiple, specifically interconnected cortical columns form ‘intracortical units’. The researchers suggest that these higher-order units are the primary cortical entity for integrating signals from multiple sensory receptors, for example to provide anticipatory information about future stimuli.
I don’t do enough of these, or any anymore, but she has helped me through so much in the past year that I have no idea where I would be without her. She’s beautiful, smart, funny, loves to chat with me late at night, I could go on and on about the things she does that I love. We’re very healthy too, it’s wonderful. There’s never been a fight, only discussions, and they’re always resolved peacefully and happily. Sometimes I watch her when she doesn’t know it, when her eyes cross slightly with concentration and she chews at her bottom lip. She’s adorable. She dresses with flair and style, even when in her relaxed clothes. She smells amazing and just the though of her makes my stomach expand to the size of the universe with butterflies. I love you hon, and I hope this doesn’t make you leak strawberry filling you tiny creampuff :D
