1.- Over 78,000 attendees joined Spring School, with 118 countries represented. The peak lecture had 17,867 attendees.

2.- Michele Romani from G-Tech presented on integrating BCI technology into games using the Unity environment.

3.- Deep learning models like CNNs outperformed classical machine learning for decoding EEG motor imagery data.

4.- Slobodan Tanackovic and colleagues demonstrated TMS-EEG experiments comparing active and passive electrodes.

5.- For TMS-EEG, the EEG device needs high sampling rates, at least 5-10 kHz. TMS artifact removal is crucial.

6.- Jack Low from Singapore discussed recording microECoG signals to capture layer 1 neuron activity for BMIs.

7.- Layer 1 neurons convey integrated top-down information. MicroECoG enables single-unit resolution over large cortical areas.

8.- Rainer Scherer from Essex University presented an overview of their BCI research on improving usability.

9.- Online co-adaptive training improved first-time BCI performance. Mental task selection is crucial for good accuracies.

10.- BCI-VR was used to visualize brain networks in real-time. Angular gyrus showed consistent changes in pilots.

11.- Firas Kassem-Moussa demonstrated projects integrating neurotechnology, AI and VR for architecture and design.

12.- EEG-based emotional states were used to adapt virtual environments. AI generated personalized spaces from prompts.

13.- Dora from Mayo Clinic discussed brain circuit biomarkers from intracranial stimulation and recording in patients.

14.- Transmission speeds across brain development were measured with intracranial EEG. Speeds increased over 2-fold from childhood to adulthood.

15.- A robust hippocampal-anterior cingulate-posterior cingulate waveform was identified as a limbic memory subsystem biomarker.

16.- Basis profile curve clustering of intracranial ERPs enabled data-driven discovery of waveform clusters linked to anatomy.

17.- Intracranial ERPs were used to track brain network excitability changes after deep brain stimulation for epilepsy.

18.- Si En Christian Reinhardt from Brainsure presented a VR neurofeedback system for enhancing ADHD therapy.

19.- The Brainsure system uses EEG neurofeedback and VR games to target attention, hyperactivity and impulsivity symptoms.

20.- A chess game controlled by focus measured through EEG demonstrated the Brainsure system's VR-EEG integration.

21.- Brainsure aims to get their VR neurofeedback system reimbursed as a prescription digital therapeutic in Germany.

22.- Mika Jiang from G-Tech Vancouver demonstrated wireless multi-device acquisition with G-Tech's Nautilus and Unicorn EEGs.

23.- Up to 4 G-Tech wireless amplifiers can be synchronized for hyperscanning. Other biosensors can be integrated.

24.- Lab streaming layer (LSL) enables real-time synchronization of multiple biosignal streams between acquisition devices.

25.- Maria Antonia Piedrahita-Valdes from G-Tech Colombia explained the principles of fNIRS brain imaging.

26.- She demonstrated how to combine wireless EEG and fNIRS acquisition and analyze the joint data.

27.- Benefits of joint EEG-fNIRS include complementary neural information and improved spatiotemporal resolution.

28.- Different fNIRS devices and software integration workflows with G-Tech EEGs were shown with live demos.

29.- Tiago Falk presented the evolution of his lab's EEG-VR headsets designed for naturalistic brain monitoring.

30.- Applications included adaptive VR games, predicting experiences, multisensory mental health therapies, and boosting motor imagery BCI with multisensory priming.
