Hirnwellen ermöglichen Einblicke ins Navigationssystem des Gehirns (A02)

Die Presseabteilung der Ruhr-Universität Bochum berichtet im Newsportal: Mittels Tiefenelektroden messbare Hirnwellen erlauben Einblicke in das menschliche Navigationssystem. Das Verfahren eröffnet neue Ansätze für die frühe Alzheimer-Diagnostik.

Das Gehirn legt eine Art Landkarte unserer Umgebung an, was eine zuverlässige räumliche Navigation erlaubt. Für die Erforschung, wie dieses Navigationssystem auf Zell-Ebene funktioniert, wurde 2014 der Nobelpreis vergeben. Nun haben Forscher des Universitätsklinikums Freiburg, der Universität Bochum – darunter Nikolai Axmacher (Projektleiter A02, A03, F02) – und der Universität Peking nachgewiesen, dass Charakteristika dieses Navigationssystems auch in Hirnwellen vorhanden sind, die mittels Tiefenelektroden im menschlichen Gehirn messbar sind.

Die Möglichkeit, auf diese Weise das neuronale Navigationssystem zu prüfen, eröffnet neue Ansätze für die frühe Alzheimer-Diagnostik. Denn ein schlechter werdender Orientierungssinn ist eines der ersten Anzeichen der Krankheit. Die Ergebnisse veröffentlichten die Forscher am 11. Oktober 2018 im Fachmagazin Current Biology.

New Year, New Me: The Facts

As the calendar turns to a new year, millions of people around the world commit to New Year’s resolutions, making promises to use the new year as a fresh beginning and an opportunity for transformation. In 2024, almost three-quarters of the British population set themselves New Year’s resolutions — that’s around 40 million people (or the entire population of Canada). This tradition was particularly strong among younger generations, with 96% of Generation Z (aged 18-27) planning resolutions, compared to just 35% of the Silent Generation (aged 79+).

Most common new years resolutions:

  1. Saving more money (52%)
  2. Eat healthier (50%)
  3. Exercise more (48%)
  4. Lose weight (37%)
  5. Spend more time with family/friends (35%)

How long do most resolutions normally last before being broken?

  • Data from America (2016) shows that 75% of individuals maintain their resolutions through the first week. 
  • 64% of individuals maintain their resolutions through the first month. 
  • 46% of individuals in America keep their resolutions past the 6-month mark.

What makes resolutions stick?

Oscarsson et al. (2020) conducted research into what makes New Year’s resolutions stick. Biggest success rates depended on how people phrased their goals. Participants who set approach-oriented goals (trying to move toward or maintain a desirable outcome or state) than those with avoidance-oriented goals (trying to move toward or maintain a desirable outcome or state) were significantly more successful (58.9% vs. 47.1%) at sticking to their goals.

The study also investigates the effects of outside support. These participants received monthly follow-ups and emails with information and exercises for coping with hurdles when striving toward personal goals, and were also encouraged to set goals using the SMART technique and to set interim goals. The group that received some support was exclusively and significantly more successful compared to the groups who received a lot of support or no support at all. 

Additionally, you might feel more successful if you set goals that are measurable in numbers. While success for a person striving to quit smoking or lose weight could easily be measured in the number of cigarettes smoked or body mass index, the success for a person striving to „take better care of themselves“ could be highly subjective and possibly impossible to measure.

So as we enter 2026, let’s remember to work with our brain’s natural learning system: Frame your goals positively, break them into manageable steps, and celebrate small wins along the way.
