Trouble with crossword puzzles? Improve your semantic memory

Can you distinguish the taste of a red wine versus a rosé? How about the look of a 1960s muscle car versus a foreign import? Do you prefer to grow lilies or tulips? Would you rather listen to Dark Side of the Moon or “Fly Me to the Moon”? To answer any of these questions, you need to use your semantic memory. Your semantic memory is your store of factual knowledge of the world and the meaning of words. It’s how you know that a fork is for eating (not twirling your hair) and what color a lion is. It’s both the source of your vocabulary and how you know what something does even if you don’t know the name of it — like that little bit of plastic that covers the end of a shoelace (an aglet). Use episodic memory to increase your semantic memory To form new semantic memories, you need to use your episodic memory to learn new information. For a week, month, or year, you might remember where you were and what you were doing when you learned a new fact. Over time, however, you will forget the context and just remember the fact. Once only the fact remains, it is part of your semantic memory. The left temporal lobe: Your brain’s dictionary Several landmark papers have examined where semantic memory is stored in the brain. In 1996, two related studies were published in an article in Nature. For the first, the researchers enrolled over 100 patients with strokes and other brain lesions in their left temporal lobe. (Put your finger on your lef...

PortelaAbstractThe Supercritical Water Gasification (SCWG) of black liquor (BL) to obtain hydrogen and dispose of organic waste simultaneously has been studied in a continuous reactor employing short residence times. The experiments were conducted at 600–700 °C, with times between 24.5–29.1 s, at 23 MPa and feedstock was diluted to different concentration levels (0.81–2.43 wt.%). Furthermore,...

In this respect, reactive primary amine of DDA molecule with high isoelectric point (IEP) could interact easily with negative charge carboxylic acid groups of OND. Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) proved that OND nanoparticle was successfully functionalized by DDA u...

In this study, CaCu3Ti4O12 (CCTO) modified polyethersulfone (PES) HF membranes were prepared via dry-wet phase inversion by adding different concentration of CCTO particles (0–4 wt.%) in the dope solution. The synthesized PES/CCTO composites were characterized by viscosity measurement, scanning electron microscope, X-ray diffraction, contact angle, pore size, and pore size distribution. The flux and the photocatalytic activity of CCTO entrapped PES membranes were subsequently evaluated by crossflow ultrafiltration and the photodegradation of Rhodamine B (RhB) under UV irradiation, respectively. The pure water ...

Conclusions:Elevated CSF Tau levels in AD patients could be surrogate biomarker for AD subtypes with predominant early cortical symptoms and atrophy. There is a need for a systematic prospective unbiased follow-up to see if rapid clinical progression in AD is related to elevated T-Tau and distinct AD subtypes.Disclosure: Dr. Pillai has nothing to disclose.

Worldwide,  nearly44 million  people now have Alzheimer's disease (AD) or related dementia, making these conditions the  top cause of disabilities in later life. The biopharma industry has invested billions of dollars into research to treat and prevent AD1, yet this work has faced many obstacles, including difficulty identifying biomarkers, tracking the disease ’s progress in the brain, and recruiting patients to trials while they are still asymptomatic. But in recent years, we’ve begun to see breakthroughs that is driving our research in new directions. Many of these accomplishments were hi...

l A Abstract Transcranial direct current stimulation (tDCS) has been successfully used in neuroscientific research to modulate cognitive functions. Recent studies suggested that improvement of behavioral performance is associated with tDCS-induced modulation of neuronal activity and connectivity. Thus, tDCS may also represent a promising tool for reconstitution of cognitive functions in the context of memory decline related to Alzheimer's disease or aphasia following stroke; however, evidence from randomized sham-controlled clinical trials is still scarce. Initial results of tDCS-induced behavioral improvement in ...
